The Single Leg MB Trunk Twist Throw is a ballistic exercise for professional athletes to improve energy transfer, neural pathways for explosive shot production, body control, balance and coordination.
The focus of the Single Leg MB Trunk Twist Throw is explosive core activation and powerful throwing motion, emulating the movement mechanics during shots, and hence leading to better performance.

MB Trunk Twist Throw Progression
If you use additional weights…make sure you use appropriate weight so you can control the action throughout the entire range of motion. Otherwise you defeat the purpose of the exercise.
Very often, people use too much resistance and they become sloppy. Especially when it comes to maintaining dynamic stability and hitting in the same spots repetitively.
Also, don’t just progress with adding more weight. First, maximize the speed while maintaining perfect form.
Here are the progression levels:
- Beginner: look down during the action
- Advanced: look up during the action and change to lunge position
- Professional: one leg action only
Single Leg MB Trunk Twist Throw Description
- Hold a medicine ball (MB) naturally in both hands in front of the trunk
- Take on diagonal single-leg stance position; knee and hip are slightly flexed; non-weight bearing knee is flexed at 90˚; back remains straight
- Rotate the trunk outwardly until shoulders are perpendicular to the wall (or as far as possible); maintain neutral head position; keep looking forward
- Initiate the throw with the hips and trunk, not the arms
- Rotate trunk inwardly until shoulders are nearly parallel to the wall
- Lean forward with the upper-body and explosively release MB at hip-level and throw MB against the wall; maintain neutral head position; keep looking forward
- Do NOT catch the rebound
- Maintain stability after the throw
