How to Progress

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 repetitively.

Also, don’t just progress with adding more weight. Instead maximize the speed and don’t look towards the ground while rotating but keep your head up and look forward. All while maintaining perfect form.

If that’s still too easy then keep your head up and track and object/person while rotating.

Here are the progression levels:

1. Beginner: look down
2. Advanced: look forward
3. Professional: look forward & track an object/person
