Takedown power comes from level change speed, leg drive, and a strong hip hinge and trunk. Train explosive squats and hinges, sled drives, and rotational work, then practise the entry repeatedly so the strength actually shows up in the technique.
A shot has a level change, a penetration step, a drive, and a finish. Each has a different physical demand. The level change needs fast eccentric control into a deep position, the penetration step needs explosive single-leg drive, and the finish needs hip extension and trunk stiffness against a resisting opponent.
Gym strength does not automatically become a better shot. The transfer happens through repetition of the actual entry, ideally in the same training block. Drilling shots on a partner or a dummy immediately after the strength session is a practical way to link the two.
Most successful takedowns are won by timing and by how quickly the level change happens, not by out-muscling someone. Train the change of levels as a speed quality, with low volume and full recovery, rather than as conditioning.
Two sessions a week, power work first, then heavy strength, then the carries and trunk work. Keep it away from your hardest wrestling days. See Power Development and Explosive Strength.
