Hanging Knees To Elbows is an intermediate bodyweight exercise for the primary: rectus abdominis secondary: hip flexors. Most lifters train it for 3 to 4 sets of 6 to 12 reps.
Hanging from a pull up bar, you curl your knees up toward your elbows rather than just your chest, forcing deeper spinal flexion than a standard knee raise. It's a stepping stone toward toes-to-bar for lifters building hanging ab strength.
Program 3 to 4 sets of 6 to 12 reps at the end of a pull day or in a core block after the main lifts. It is a strength exercise for the abs and hip flexors and a progression toward toes to bar, so it needs fresh grip and a stable shoulder.
Set up from a dead hang with shoulders packed and let the body stop swinging before each rep. Bodyweight is the starting load; progress by holding the top position for two seconds, then by moving to straight leg raises or toes to bar once 12 clean reps are easy. The most common fault is kipping to reach the elbows; fix it by pausing in a still hang between reps and lowering the leg height until you can reach without a swing.
They work the rectus abdominis and hip flexors most, with the obliques, lats and forearms stabilizing. The high knee position adds more spinal flexion than a basic knee raise.
Aim for 3 to 4 sets of 6 to 12 strict reps. If you can do more than 12, move toward toes to bar rather than adding reps.
Toes to bar is harder because the straight legs lengthen the lever and demand more hamstring mobility. Knees to elbows is the standard stepping stone and trains the same curl of the pelvis.
They are safe when the shoulders stay engaged and the body does not swing wildly. Keeping the lats active and avoiding kipping protects the shoulder joint.
