The calisthenics flex everyone wants. Years in the making.
Keep your elbows locked and body dead straight. Bent arms shift the work off your lats.
The front lever is a full-body isometric where your core is the load-bearing bridge, holding your entire body rigid and horizontal while you hang from straight arms. Your abs and everything around your trunk work brutally hard to stop your hips folding, with your upper body pulling down through locked elbows to keep you parallel to the floor. It is a benchmark move in calisthenics because it cannot be faked, you either have the straight-body strength or you do not.
For most people, months to years of consistent progression work, not weeks. Time in tuck and advanced tuck holds, plus straight-arm pulling strength, is what eventually buys you the full lay.
Work the chain, tuck lever, advanced tuck, single leg, then straddle before full lay. Hold each stage with locked arms and a dead flat body for 15 to 20 seconds before moving up.
Sagging hips mean the core is losing the fight or the body line was never set. Squeeze your glutes, posteriorly tilt your hips, brace like you are about to be punched, and regress to a version you can hold perfectly flat.
