Nice! It's really helped my knees! Haven't noticed much very maximal gains but I have found some SL bounce again (then again I've been training for a minute now. Lol)
I think the biggest benefit of the program is getting knees and ankles healthy and allowing you to jump at a more consistent level. That's been my experience so far. I haven't trained consistently the last 3 months though so looking forward to getting back to my previous level.
I will be interested to see where it takes you though Chris given your already high level of vert.
I think it should at the least balance my jumping (improving other plants). If it adds inches I'm STOKED for that but it's been a blessing for my knees already so worth every penny IMO.
LT3976, I still do some jumps in my warmups altho volume is way down. I'd LIKE to get some real jump sessions in but life is hectic currently. As long as your approach is solid in regards to not overdoing the jumping and quality>quantity I think you should be able to have a few jump days.
