Regaining &inproving top speed

I’d stay with 2 foot ankle type pops. Anything with one leg will cause you to flatten out initially. Just go as high as you can get a good ground reaction from. Usually in sets of 10 hops with breaks to be sure not to build up any fatigue before the sprints. There is usually a response after 2 or 3 sets but keep going up to 5 sets if you keep getting a higher response and stop as soon as the response levels off. Leave the hurdle hops till later on.
It’s hard to predict when the carry-over from the weights will kick in. In fact, the response may already be waiting to happen and only needs the foot reaction/ground response to fall into place to take effect.
I have always preferred flying 20s because that’s the longest most people can ever hold a true max speed and I want to stay out of a fatigue state for as many quality reps as possible. I always wondered why flying 30s were so popular.
