Heavy KB Swing/T2B Couplet Workout

Skill
5 Ring Muscle-ups PR
I finally got the technique down. It turned out to be easier with a hook grip.

WOD
3 rounds for time of:
10 Heavy Kettlebell Swings (28kg)
30 T2B
This was really tough on the core.

Endurance
3x400m (2mins rest)
1:26 - 1:23 - 1:20
Since my first 400m wasn't as fast as I wanted, I decided to increase the effort each time.
