Why should you give interval training a try? “This is what I do after my workout to get my muscles tight, burn excess fat, and even how I train for a 5K (without EVER running the full 5K prior to the race!),” personal trainer Jane Grieme says, “You WILL see results! Do this POST workout 3 times a week for 4 weeks – then let me know your results!”
What makes HIIT work so well? One factor is the type of muscle fibers used. “HIIT recruits large, powerful muscle fibers that otherwise lie dormant,” says Martin Gibala, PhD, a Kinesiology professor at McMaster University. The training perk? Faster fitness gains, including more noticeably defined muscles. Try the interval workout charted above on a treadmill, elliptical or recumbent bike, and don’t forget to let Jane know the great results you achieve!
