Row/SkiErg or alternate 5 minutes
In between each row or ski do:
- 10 kettlebell swings
- 10 sit-ups
- 10 push-ups
- 10 air squats
Repeat until you have completed two 5-min rows and skis.
This is a great workout to partner on, too. In that case one partner rows while the other skis, then you switch.
