Consider a progressive strategy to build the requisite strength and control for toes-to-bar repetitions. Here is a sample exercise progression using Variations discussed above: Start by training your hip flexors and abdominals at short muscle lengths using hanging L-sits. Add long muscle length work via controlled GHD sit-ups. Strict toes-to-bar, although difficult, may be possible before kipping toes-to-bar, because they are less complex. Practice the forward and back (arch to hollow) kipping motion, in isolation without the leg raise, on a pull-up bar. Once proficient, it’s time for the real-deal toes-to-bar.
