Want a great summer time change-up to your aerobics regime?
Can you imagine a challenging workout that works and refreshes? Ever wonder why Michael Phelps eats 12000 calories? Calories are a measurement of thermal units or to put it another way; Calories measure heat. Jump in the water and do your thing and guess what? You are exercising in a giant heat sink. Phelps does all his training in water and must eat more to replace the calories lost from heat dissipation.
