Hello.
Changing from 1/2 leg lift to negative seems all but impossible to me.
I'm able to easily do the 1/2 hanging leg lift the prescribed number of times and while it's tiring for my abs I've completed the mastery as prescribed.
Now the problem comes when I try to do the negative leg lifts, I literally cannot get my hips high enough to create the position found in the Foundation 1 video. My abs give out, not that they are being used and then suddenly they cannot hold, literally when I get to a certain height my abs feel like they aren't doing anything.
It's hard to explain the feeling, but imagine if you tried to do a Planche while still working on Foundation 1 skills, you know that feeling when: yeah, you were trying but your arms gave out like you weren't doing anything? That. That's the feeling I have.
Why does this happen? Am I doing something wrong?
