The Inventor of HeavyHands, Dr. Leonard Schwartz

Dr. Leonard Schwartz, the inventor of Heavyhands made millions on his patents, best selling books and licensing deals to AMF Sports and others.

I’ve been in the business of manufacturing and selling hand weights from my site http://www.WeightedHands.com for the last several years.  This exercise system is one I have been testing all along and it’s helped me drop 12% of my body weight over the last few months without destroying my back, knees and feet.

Millions of the little red sets of Heavyhands weights were sold in the 1980s.

Here’s an inside look at the story of HeavyHands and how Schwartz says working out with them can change the way you age.

Exercise enthusiast, Neil Myers, struck up a friendship with Dr. Schwartz years ago after reading how the late doctor used HeavyHands to decrease his pulse rate from 60 to 38 and his body fat from 14% to 4%.

Neil had only heard of elite athletes with numbers like that (not some guy in his 50s), so he contacted the doctor to find out more.

That was the beginning of a lifelong friendship that would change the way Neil viewed aging.

Dr. Leonard Schwartz didn’t believe that the musculoskeletal system needed to decline as we age.

He believed that working all four limbs at the same time, instead of just two, would allow feedback loops from the heart to the muscles to form and strengthen, preventing sudden overloads on the heart while also preventing muscular declines in strength and movement.

And in this audio interview, you’ll get an inside look at the inventor of the HeavyHands workout along with tips on the best exercises to do with the weights and how Dr. Leonard Schwartz intended they be used to improve your life.

You’ll Also Hear . . .

•  Why Dr. Leonard Schwartz called swimmers and cyclists “gravity cheaters” – and how to use the resistance of gravity as a way to make workouts even more beneficial

•  Why Dr. Leonard Schwartz didn’t believe you needed to lift heavy weights to improve health and strength – and a quick look at how he came up with his HeavyHands fitness concept

•  Debunking the hero myth that you need to “push through the pain” when exercising – what your body is really telling you and what to do instead

•  The real problem with “repetitive exercises’ and how simple changes to your HeavyHands workout can result in a whole new fitness routine – with changes in speed, cadence, angle, direction, and weight

•  What Dr. Leonard Schwartz considered to be one of the most important concepts to learn about fitness: “long-strength training.” What that means and how to make it a part of your routine

•  A step-by-step look at how to do one of the single most difficult movements of HeavyHands, and why you may want to give it a try

•  How long it usually takes to build a virtual “fat-burning furnace” so you’re controlling your weight with energy, strength, and stamina (without really trying)

As a hypnosis practitioner, Neil works with clients to improve their health and well being.

He says he recommends the HeavyHands workout to all his clients because it’s so versatile.

It doesn’t matter if you’re already an elite athlete or a couch potato, no matter where you are in life, there’s a place for you to start and get immediate benefits from the workout.

Even in his 80s, Dr. Schwartz was able to do things most people in their 30s would be happy to be doing.

And in this interview, you’ll hear all about him.

Voyeurs Advice For The Weighted Hands Neophyte . . .

New to Weighted Hands?

Want to turn regular walks into calorie-burning workouts?

Then you MUST read every word of this true story below.

Here’s what it’s all about . . .

Terry been walking with Heavyhands for over 25 years.

He started doing Heavyhands back in 1978 when he developed arthritis in his two big toe joints and couldn’t run anymore.

He was frustrated as hell because no other workout was helping him keep the weight off like cross-country running.

Then he saw Dr. Leonard Schwartz’s book Heavyhands at the books store and thought he’d give it a shot.

So he started walking with Heavyhands and changes were happening fast.

He immediately noticed muscle definition in his legs and arms similar to what he had when he was running, and he hasn’t looked back.

And in this audio, you’ll hear how easy it is to incorporate Heavyhands into your fitness routine even after injury or arthritis.

You’ll Also Learn . . .

• Exactly what Terry noticed when he quit doing Weighted Hands during the winter months because of the cold – and what he does now to keep Weighted Hands a part of his year-round routine

• A quick look at Terry’s modified workouts: how he incorporates Weighted Hands into his running now along with other exercises he does too

• Exactly how long you need to work out before you see results

• Clear and straightforward advice for anyone starting out

Terry says the increased calorie burn of the Weighted Hands workout has been the only thing remotely similar to the results he got running long distances – but without the strain on his feet or the drive to the gym.

And in this audio interview, you’ll hear how he’s started using Weighted Hands to do that, so he’s turning his regular walks into calorie-burning workouts.

Decade Old Questions Answered On Heavyhands . . .

This is cool.

I found an interesting Q&A exchange with the inventor and developer of Heavyhands and a long time Heavyhander in the archives of an old Heavyhands blog run by the old distributor of Heavyhands.

This was at a time, over a decade ago, when Heavyhands was poised for a comeback into the mainstream of America.

Here is the question . . .

Hello, and Happy New Year to all

I am a retired pathologist living in Cape Town, South Africa

Len Schwartz has been an inspirational eminence in my life since 1984 when I was 38 years old. A moderately good but rather heavily built recreational runner (10k in 34:15; marathon 2:50; 170+lbs at 5’10)

I happened upon the first HH book in a local bookstore in Upstate NY and the B&W photos of the 57 year old were an epiphany.

That was the kind of body I wanted to have

The exercise physiology expounded seemed plausible.

I bought and experimented with a selection of generic dumbbells 1-15 lbs.

And quickly I made great improvements in my upper body endurance and strength.

Before I could test whether the enhanced muscularity of upper body was detrimental to my running, I tore a meniscus in my knee playing racquetball.

This was in the early days of arthroscopic surgery.

I couldn’t run for over 12 years without knee pain.

But I kept up religiously with HH walking medleys with lots of double ski poll exercises in particular

I, too, rarely ever saw anyone else doing Heavyhands right!

At age 50, I gingerly started running again as my knee pain seemed under control and entered some 5ks/

Interestingly, my age adjusted running times were several notches higher than almost a decade and a half earlier.

I was matching and often easily beating my erstwhile nemeses who had continued running and training hard all the while.

Now retired, I have recently taken up competitive race walking, a very challenging sport, but one far more suited to my (panaerobically conditioned) physiognomy.

Whereas I was an 84% level 53 year old runner (national class), I am a 90% level race walker at 57 (3k in 14:00 in judged competition – world class for age)

Clearly, quite consistent intense training with HH over 15 years has in my case been crucial in mitigating the usual or expected age related decline in aerobic capacity.

Aerobically trained upper extremities are a definite advantage in race walking (as predicted by Leonard Schwartz in his walking book)

A few questions for LS (I have many):

Len, would you say your originally rather heterodox ideas have now entered the mainstream in exercise physiology circles, or are there still doubters?

What was your (amazing) combined VO2 max of ~ 80 at age 57 estimated at?

What has been your personal experience with respect to VO2 Max decline in your 60s and 70s

What about your % BF and MHR/RP?

How recent is the great looking color photo on the HH website?

Responses to the questions posed by N.F. from Len Schwartz

N.F.: Would you say your originally rather heterodox ideas have now entered the mainstream in exercise physiology circles, or are there still doubters?

Schwartz. My guess is that the infiltration is both spotty and iffy! It appears that this ‘heterodoxy’ has been either bypassed or over a short time frame-adopted as the only way to go. This feast or famine quality may have to do with the fact that Long strength hasn’t really been presented to the public so that men and women would get involved. Same applies in physiologic circles. It appears that the folks at the University of Pittsburgh are eager to reengage = Heavyhands (Panaerobics-Longstrength) research. There are many interesting pockets of doubt, just as in all the basic areas of fitness/exercise research, but that’s where the fun lies!

N.F. Why was your (amazing) combined VO2 max of ~ 80 at age 57 estimated?

L.S. As I recall, we had measured my 02 pulse at various levels of continuous intensity earlier. That made it feasible for me to estimate V02s by merely pulse counting. With later direct measurements (many) this level was reaffirmed. I remember one level of 70 ml/kilo/min-1 was directly measured at a pulse of less than 120/bpm! A famous U.S. physiologist, looking at my findings was prepared to say that was indeed a most high test! Actually, given the likelihood of the reentrance of genetic and technical issues I make much less fuss about V02’s. We do what we can, period! More important, I think are those sub maximal V02s which is where the work of exercise is accomplished!

N.F. What has been your personal experience with respect to VO2 Max decline in your 60s and 70s

Schwartz. Surprisingly little, if any decline. A couple of years ago I did walk ‘n’ pump treadmill test that appeared to be as high or higher than that direct test.  The literature indicates that there is a fall off in performance among aging, regular, aerobic type athletes. I do believe that eventually Long strength type athletes will record some of the highest sub maximal performances. These could well be accomplished by athletes who handle heavy weights while doing  comparatively many repetitions (perhaps a thousand or more), within the aerobic sphere. The work of Pavel Tsatsuline at Dragondoor is fascinating in this respect.

N.F. What about your % BF and MHR/RP?

Schwartz. Perhaps 3-5% at my petite 130lbs! Resting pulse 40-50.

N.F. How recent is the great looking color photo on the HH website?

Schwartz. Pretty recent, within 5 years.

Weighted Gloves May Alleviate Bone Mineral Redistribution

Weighted gloves may alleviate bone mineral redistribution

THE CAPITAL TIMES, Tuesday, April 3,1984

Are “Heavyhands” weights and weighted fitness gloves gimmicks?

Or will they prevent runners from behaving like mule deer?

Researchers discovered in 1973 that something odd occurred in mule deer when they developed antlers.

Bone mineral was lost from unstressed areas of the deer, such as the ribs, and redistributed to the growing antlers.

Ten years went by before the significance of the bone mineral redistribution phenomenon really became clear. Its importance emerged in research by Dr. Everett L.

Smith, director of the University of Wisconsin Biogerontology Laboratory.

Smith was studying osteoporosis, the loss of bone mass during aging. Osteoporosis is a major problem for older women, who suffer fractures as their bones become more and more brittle.

The impact of exercise on bone, which behaves much like muscle when placed under stress, was already known.

Studies showed distance runners had 20 percent more bone mineral content in their femurs than on-runners.

Professional tennis players were found to have thicker humeral bones in their playing arm – 35 percent for men and 28 percent for woman – than in their non-playing arm.

At the same time, studies of astronauts showed they lost 7 percent of their heel bones during only 10 days of weightlessness in space. People on bedrest for 36 weeks showed a loss of 39 percent of their bone mineral content.

Smith studied groups of women ages 35 to 95. His studies showed that a combination of exercise (aerobic dance) and good diet (with adequate calcium and vitamin D) reversed the women’s loss of bone mass, which normally accelerates after menopause.

In one three-year study, the control group lost 3.29 percent of their bone mineral content while subjects on a calcium-vitamin D supplement gained 1.58 percent and those on an exercise program gained 2.29 percent.

In another three-year study, the control group lost bone mass at a rate of 2.44 percent, while an exercise group gained 1.39 percent.

The gain was not constant, however.

Smith, who was using a device that measured bones in the arm to gauge mineral content of the subjects, found the exercise group experienced a drop in bone mass the first year before scoring gains in the second and third years.

The unexpected initial decline was eventually determined to be due to the calcium redistribution mechanism like that found in mule deer.

Women placed on an aerobic dance program stressed their legs, for which calcium was taken from unstressed areas like the arms.

The femur thickened, while the ulna and humerus initially weakened.

Smith said the skeletal system behaves like the muscular system. Both adapt to the stresses placed upon the body.

“If you don’t use the human body, not only do you waste muscle mass and the heart, but you also lose bone,” Smith said.

Osteoporosis is mainly a problem for women, who lose 30 percent of their bone between the ages of 30 and 70.

Men start the aging process with about 40 percent more bone mass, lose it at a slower rate and usually don’t have a problem with weak bones until their mid-80s.
With aging women suffering 150,000 to 200,000 broken hips a year in the United States, getting them to exercise could have a big impact on health care costs.

Smith estimates the bill for their hospital care alone is about $1 billion and, when nursing home care and other costs are added, the total price tag for osteoporosis is about $3 billion a year.

What the calcium redistribution effect indicates, however, is that aerobic exercise like dance or running is not enough.

Weights are also needed to maintain the upper body and Smith now recommends a routine that includes use of wrist or hand-held weights and pulling on surgical tubing attached to a post or wall to prevent redistribution.

The evidence seems to support the “Heavyhands” devices and weighted gloves sold for running.

If you don’t have time to get in upper body workouts separately, they are probably the way to go.


Thankfully entrepreneur Michael Senoff of www.WeightedHands.com began producing replacement weights and also specialized ergonomic handles for “HeavyHands” exercise, the prospects for finding new equipment were virtually nill.

Now, thanks to Senoff, the HeavyHands enthusiast can progress from the smallest weights used at the beginning to the heavier weights required for maximum strength endurance development.

Finally, people are able to progress as far as they want using HeavyHands.

Once again, Dr. Schwartz’ proven methods are helping a new generation of exercise and weight loss enthusiasts.

Dr. Schwartz’ Exercise Patents

Dr. Schwartz’ Exercise Patents

schwartzhandclaspOne newly “mined” source of information about Dr. Schwartz’ progress in thought regarding Strength Endurance, Panaerobics, Isotonometrics, and Long Strength, and Panaerobics comes from patents filed with the US Patent Office on a variety of topics

Of course, there are the original patents for his “HeavyHands” weights called the “Apparatus for exercising that is used with a hand“ or “Aerobic Hand Weights” in the patent filings, but in this blog, the patents of most interest are the ones related to Schwartz’ strength endurance methods, a strength endurance exercise device, and even the method of clasping his hands as he performed weight free four limb exercise!

The author continues to discover them and “decipher” them … if the reader knows of others, posting such links in the comments would be greatly appreciated!

“Fitness Method” (Hand Clasps)

This method came to be known as “isotonometrics” as far as this writer can tell. The image at the top of this page comes from this patent filing. It used hand clasps instead of weights to produce a similar effect for anyone who did not care to use weights for whatever reason. Once one sees Dr. Schwartz working out “in place” in this heavyhands video at DailyMotion, it is simple to imagine these or similar movements joined to the hand clasps described in the patent at the link.

Here is how Dr. Schwartz described his method in the patent itself:
A fitness method for an exerciser combines the benefits of isometric-like exercising with isotonic exercising for simultaneous training of the exerciser’s cardiovascular and skeletal musculature systems and strength and endurance buildup. The method entails coupling the exerciser’s hands together in any one of a number of configurations and generating an isometric-like force during the coupling stage. The coupled hands can then be moved in any number of directions or coupled differently while maintaining or varying the isometric-like force during the movement. In addition, further training can be achieved by moving one or more other body parts during the coupled hand movement. The legs, torso, shoulders, and/or neck can be moved in any number of directions or sequences to exercise different muscle groups in conjunction with the muscle groups being worked by the movement of the coupled hands.

Alternatively, author Marty Gallagher – friend and admirer of Dr. Schwartz – describes his adaptation of the “isotonometrics” principles adapted from Dr. Schwartz’ findings in his chapter on “Third Way Cardio” in his book “The Purposeful Primitive”.

“Strength Endurance Method”  and

“Strength Endurance Exercise Apparatus”

These related patents describe first the “Method” and then the suggested “Apparatus” for developing “strength endurance” (aka “Long Strength”) through the use of four limb bodyweight exercise using the patented device Dr. Schwartz developed.

While thousands of handweights were in production after Dr. Schwartz’ book, Schwartz student John McKean said only three of the devices described in the patent were ever made. It was called the “Pan-X” machine.  Once the patent’s images are seen, it’s obvious that Dr. Schwartz’ device would have had strong competition from today’s “Suspension Trainers” or “Power Tower” (i.e. dip and pull up station)

Here is how Dr. Schwartz’ patent filing represents what he was trying to accomplish:

In an alternative embodiment, the present invention is related to a method of exercising which uses both the arms and legs to perform sustained aerobic and strength conditioning movements…. In a preferred embodiment, the rhythmic bipedal movements includes jogging.The rhythmic bipedal movements can also include scissor kicking in a forward/backward direction or in a sideways direction. Alternatively, the rhythmic bipedal movements includes alternate leg lifting. Preferably, during alternate leg lifting, the user dips on his stationary leg. Leg lifting can include kicking in the forward direction or kicking in the backward direction. In a preferred embodiment, forward kicking includes the step of high knee kicking. Alternatively, alternate leg lifting can beperformed to the side. In another preferred embodiment, the rythmatic bipedal movements includes the step of leaning from side to side…..

Students of Dr. Schwartz will find good information in these patents to help understand his thinking in the development of exercise that did not rely on weights to achieve excellent aerobic and strength gains. While they are not as precise as a book might be, they do spark the imagination and allow the potential user to derive exercise movements from those explicitly listed, or discern underlying principles so that other exercise combinations might be created by the individual user as Dr. Schwartz anticipated.
