This nasty combo destroys your legs and lungs and is surprisingly taxing on your upper back as you struggle to hold the position. It’s best performed on leg days as a finisher.
How to Do It
- Do 5 kettlebell swings.
- Without rest, do 5 goblet squats.
- Again without rest, do 5 step-back lunges per leg.
- Repeat as many times as possible in 8 minutes.
