One Minute Work Outs

The above link is to a great article about the value in high intensity training.  

"A recent study published in PLOS ONE reported that men and women who performed three 20-second all-out high-intensity intervals on exercise bikes three times a week for six weeks boosted their muscles’ mitochondria (the energy-producing furnaces in the cells) and increased their endurance by 12 percent. Yes, the folks in this study were fairly sedentary, but when I called study author and longtime high-intensity interval training researcher Martin Gibala, PhD, of McMaster University in Ontario, he confirmed that research shows even highly trained athletes can make greater gains when they swap volume for intensity."
