Follow the front lever isometric exercises in the video. Use additional resources for other front lever isometric exercises.

3 sets of front lever hold at a slightly easier progression than Tuesday, aiming for 10+ seconds per hold. For example, if Tuesday was one-leg, today use a tucked front lever or one-leg with a bend, to accumulate longer hold times.
Alternatively, do front lever raises (from hanging, pull up to an angled front lever and hold briefly, for 3–5 reps a set) if static holds are failing early.
Rest: ~2 min. Longer time-under-tension builds strength endurance in lats and core for the front lever.
