How to scale the Mountain Climber
If you can't do the movement cleanly yet or the workout is too heavy, use one of these variations:
- Slow, without hopping
- Hands elevated on a box
- Fewer reps
These descriptions are general guidance and don't replace a coach. Have someone at your box show you new movements, and stop if anything hurts.
