L hangs for abs

If I was to do L hangs just solely for abs what would be the right amount of time to do them for

IanO,

Perhaps you can work hanging Ls like the front lever progressions: do an aggregate of 60s. But, in my opinion you would probably get a whole lot more bang for your buck if you did reps of hanging leg lifts or worked on the FL progressions rather than just holding a hanging L. I'm guessing that if you hold hanging Ls for time, your hip flexors might give out faster than your abs will.

There is a reason we work hanging L, it's right before we train hanging V. The ability to hold the hanging V is what helps many kids make their kips and hold their toes to the bar on the upswing phase. The ability to hold the L shape is important in learning the glide swing. Not everything is about the isokinetic action. We have to teach gymnasts to hold each shape/position perfectly.

Training the L hang, also helps in the L-sit as it isolates the movement in case their support strength is weak.

Once you can hold the L hang for 15-20s, you could probably work Hang V according to the SteadyState principles.
