At Men's Health, we're using this period as an opportunity to build up our community and share as much useful, positive information as possible. For everyone stuck missing their typical workout routines with gyms and fitness centers closed down, we've done our best to provide as many at-home workout options as possible . But that's just the start. We're also hosting live workout sessions on Instagram with some of our favorite trainers to fill the fitness class-shaped void in your daily routine.

Gerren Liles , founding Mirror trainer and creator of All Out Studio 's High Power HIIT program , hosted the latest session. His HIIT workouts are designed to cram as much safe, effective work into as little time as possible.

But instead of strictly regimented work and active rest periods, Liles is pushing the effort for most of the period in progressively longer rounds. You'll start with short 30 second work periods, then extend to 45 seconds, and finish with all out effort for a full minute.
