Ever since April of 2013 I've been in awe of the front lever. I thought it was the most amazing skill on a bar and decided to start training it consistently. However, the only way I trained for it was by doing static holds of the progression I was on. I started with the tuck hold and made my way to the adv. tuck. Although after training for months towards the straddle front lever, I just could not get my legs out. I did not have adequate core strength so my legs always piked.
After stopping FL training for awhile, I later worked the negative body levers for a few weeks. Just for fun, I attempted a straddle front lever, and I COULD FINALLY HOLD IT!! Only for 2 second but with clean form.
Just saying, the body levers are seriously amazing.
