‘Runner’s Knee’ pain/injury prevention (via competitor.com)
This is a good one. I’d normally do it without the step But actually, the step is a REALLY good idea. You can also vary the exercise with the non-supporting leg going to the back/side and at 45-degree angles. To aid recovery, rub CBD cream in the area hurting.
In the video, the supporting knee wobbles slightly. Try to avoid. If yours wobbles then you need to work on this.
