I didn’t think this was supposed to be a strenuous position, so I assume I’m positioning wrong:
On my side, I press my knee into the bed to prop my waist up slightly (kind of like a mini sideways plank) so that I can thrust properly.
But pretty quick I tend to feel a cramp coming on in the glute closest to the bed.
Thoughts? Am I doing things wrong or do I just need to hit the high rep squats?
Thank you 🙏
