Here's one of my favorites.
Go heavy with the bell!
Get as many rounds as you can in 15 minutes of:
- 5 pull ups
- 10 Ring push ups
- 15 Kettlebell swings ( I used a 32kg bell)
Try to hit 10 rounds on this.
This ia a great way to get a lot of work done in a short period of time while hitting just about every muscle in your body.
