We get it: Sometimes you just don't have enough time in the day for a 60-minute spin class or lengthy session at the gym. The good news, though, is that you can still work up a sweat even if you're traveling or having a crazed week at work. These super-quick moves from Alonzo Wilson, founder and director of training at Tone House in New York City, are designed to deliver maximum calorie burn in a short amount of time (think: less than a minute) so you can fit in a workout even on your busiest days. And as an added bonus, each of these challenging HIIT-inspired exercises can be done right in your living room and don't require any gear. Do just one or complete them in a sequence.
