This is interesting its a fitness regime that incorporates just three minutes of exercise a week but claims to make you fit. Called High Intensity Training or HIT it involves doing short bursts of high intensity exercise for just three minutes a week over a four week period. The exercise involves warming up by doing gentle exercise on an exercise bike for a couple of minutes before going flat out for 20 seconds. After a couple minutes have a rest and then do another 20 seconds flat out. Another couple of minutes of gentle exercise and then a further 20 seconds of flat out exercise. This regime is supposed to use more muscle tissue than classic aerobic exercise using not just the leg muscles but also use the upper body including the arms and shoulders so that 80% of the body’s muscle cells are activated rather than just 20 to 40% for walking or moderate exercise. I’m not entirely convinced but does make for interesting reading.
