All you need for this quick workout is 8 minutes and a kettlebell. Check it out.
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.
