Get Ready to HIIT It With One of These Tabata Workout Videos

After a quick full-body warmup, this workout alternates between just two moves — squats and push-ups — for eight rounds each. By jumping into push-ups after doing squats, your legs get a longer rest while you work your upper body. The only catch is, you do this for eight minutes total. It's challenging but oh so good.
