The highest VO2 maximums ever recorded by a group of athletes were not registered by endurance runners, which is what he had logically presupposed before his investigations, but rather by Russian and Norwegian cross-country skiers. Why was this? He wondered. It didn't take long for him to come up with the answer: the skiers generated propulsion using all four limbs. The runners used only their legs. While the majority of the aerobic world used two limbs, the legs, in their respective modes, the skiers were using four limbs to power locomotion. The poundage possibilities were limitless. A person moving a pair of 20 pound dumbbells short distances for 10 minutes would net far different results than a jogger throwing 2 pound hand weights head high for 60 minutes. Len's own transformation was mind-blowing and pointed out how effective the studies use of quad-limbed cardio exercise could be ... (Followed by a table of resting heart rate details) "The elite marathoner runs at approximately 75% of his maximum workload capacity. A Heavyhand user can generate 50% of leg capacity, 50% of arm capacity and exceed the marathon runner's 75% of maximum capacity using legs only. This is why Heavyhands feels easier. Lots of units, each doing less, add up to more."
