Guys, I'm having a nice time with these. PE is fair enough, not hard to get 30s. But since the very first rep of the iM, I get severe cramps on the back of the legs. It cripples me severely and I just can't keep going with the rep.
I know I don't bridge as much as the model, and that's probably why I try to lift by the end (instead of all along) the rep.
What can I try to avoid these? My guesses are based on the premise I'm either not neurally adapted or muscular enough, so:
- Bridge with two legs reducing legs input (there's a bid difference on the bridge angle from this iM and the previous 2-legged one)
- Scale down iM to the point of no cramps (don't rise to fullest)
- Grease the groove daily for 1 rep a few times a day (until the point of no cramps)
- Try variant on medicine ball
I do a very similar exercise on Pilates, but using rings instead of floor. Could it be that rings work for stability and pull are so very different from the traction to pull along the floor?
Note: the floor seems good enough for doing planche leans, as my support slides gently. But on this exercise, probably due to the huge load on feet, it doesn't slide very smoothly.
