I recently got a plyo box for developing so-called “explosive strength”. Ok, I don’t quite know what that means or that I need it, but my running seemed to have plateaued and strength exercises like plyo jumps feel to me like they are stressing and strengthening the right parts of my posterior chain that probably get insufficient attention otherwise.
Any tips on how to approach plyo to avoid strain injury? I got plantar fasciitis the week after I first started doing very modest plyo at a park bench near my place (before I purchased the box) so I have this uneasy association in my mind even though I hardly know that that the plyo and PF are connected. I usually do one or two sets of 20 jumps on to a 20” box and slowly step down after each jump. I’m hoping to increase reps and/or intensity over time.
Any other tips based on how plyo helped you if it did? Any recommended workouts? Do you run on days you do plyo or do it only on cross training days?
