One of the most useful exercises are the negatives. The muscle is a lot stronger doing the eccentric part than the concentric part of the move. So I incorporated them in my training. And I clearly noticed good progress.
These are some of my negatives, my first attempt was of course, fail, I was not strong enough to do advanced tuck negative.
After few weeks of hard work I finally managed to do advanced tuck negatives, I got stronger and I could do them very slow.
I also tried straddle negative, in which I underestimated myself. I was not strong enough.
