Hi guys,
I don't know if this goes in this forum but my question is, how to develop the strength to keep the back straight in some exercises? For example the box press of handstand 2, the hanging leg raises, tuck planche or frog stand. When I have to hold some positions with the back straight I have a hard time, for example in frog stand which is something pretty easy my hips don't go that high, the same with tuck planche, my butt goes in and my upper back rounds too much.
I would really appreciate if you can send me some homework to work on that, I guess is lack of core strength but I don't know good exercises to improve it because the old plank and front support positions I can hold them for minutes.
