Double kettlebells.
5 Swings
5 Squats
5 Cleans
5 Thrusters.
Try and do that without putting the bell down. Rest three minutes between rounds. Go for 6 rounds.
I did this with double 16 kg bells. I admit I had to put the bell down once, after the squats, on rounds 4-6. But I did finish all the movements and rounds. This was very difficult and I bet I will feel it tomorrow. Trevor's workouts always bring a little bit extra.
