Thank you! I appreciate yousharing your perspective. For rapid twitch training, the key will be training at high velocity. Any movement, including the primary lifts, can be trained at maximium velocities. Keeping your RPE between 4 and 6 is a great way to build strength while reducing the rigors of heavy training. For isolated striking movements, you could use a cable column or barbell landmines to replicate rapid single arm pressing. For legs, a seated knee extension or single leg hip thruster would work well.
