I have a bit of experience with frustration in vertical leap improvement.
I have been working with BrandX personal trainers remote with workouts and progress monitored through email and this site. My specific goal is to improve vertical. I’m 6’1” tall and 40 with about 18 months of crossfit under my belt. In a collegiate era I was able to dunk and played setter in volleyball. Last fall on a USAV men’s BB team (middle level volleyball 6 man indoor) I found I was having trouble playing middle blocker and then realized I could barely grab the rim of a normal 10 foot basketball goal.
I have been on five weeks of the BrandX programming and the project to improve vertical is very work intensive. In past life exercise, I tended to rely on oversized calf muscles and springy legs with little hip drive for vertical and as my body fell apart it was clear this wasn’t going to work anymore. My goal is to get back to dunking and the five weeks of training has focused very intensively on:
1) Improving form through hip and hamstring flexibility so that the full range of motion is utilized in the workouts that are presented
2) Improving strength in Deadlift, Squat, and the combination lifts from the ground overhead (clean, snatch and versions of press including Jerk and different presses). This is the really intense work function of the exercise and it is a daily grind that would be easy to “just not do or do later” if I didn’t feel committed and have someone checking the progress.
3) Incorporating WOD programming right along with the strength that stresses the quick firing.
One would think that there would be a lot of the typical “running stairs, step ups, box jumps and calf raises” and there are plenty of jumping parts to the metabolic conditioning. There are also loads of short burst sprints, small set high box jumps, broad jumps, kettlebell swings, and simple double under practice and these never replace the strength nor does the strength work replace the explosive fitness work; I have to do them both.
I know the metric for vertical will be how high can I jump but I can tell you that the change from struggling at 95-120 lb deadlifts to 3 rep max of 160 lbs at the end of a hard workout and similar improvements in squat and clean have me able to simply stand under a basketball goal and with a casual bend and good hip drive get my wrist at the rim. Volleyball starts up again in March so I feel well prepared for the game.
It is interesting to me that the improvement actually came not with a bunch of added jumping and agonizing over vertical leap but with a dedicated series of challenging grind workouts day in and day out for five weeks. But I would not have been able to focus this kind of change without some review of weaknesses and the guidance.
