Just one of the several fundamental errors with Scooby's training right now. 
Just trying to cut down the fat and adding reactive strength this very moment.
2 more weeks to get Boing over with and I should be back with Weight on my back.
On the other hand, Some body got me a copy of FLYINGin4weeks training program. I found out many of the exercise is similar to BoingVert. Exercise like Fire Hydrate, Plank and various stretching exercise...
I should be back in doing Heavy squat, deadlift & jump squat very very soon.
Mean while, I hooked up with a 4 yrs successful vert trainer from Taiwan, andykyo32 on youtube ... i hope can get some feed back from him also.
Scooby, why are you falling into the same trap again? The absolute best thing the trainer could tell you is what everyone here has already been telling you, and what you
repeatedly acknowledge you should already be doing!!!
Flying in 4 is a scam, for your own sake don't even think about wasting your time on it:
http://www.verticaljumping.com/flying_in_four.htmlTo be completely honest, I think you should take the pressure off yourself in regards to dunking by November. It sounds like you're still 5-6'' off if you're only getting 1 inch above a "slightly higher" rim.
Go back to basics for a bit: squat heavy, strengthen the other major muscle groups, 1-2x jumps practice a week, and maybe some sprints, plyos and low-level volume of "shock" plyos like depth jumps (15-30 x2 sessions a week is too many IMO) on another day. Then when you've got your strength up in squat, deadlift, whatever, you can move into more explosive stuff and practice max effort jumps/dunks with smaller ball more.
Just my 2 cents, feel free to ignore it, but realise that most people are calling you out lately because they don't want to see a fellow vert athlete wasting their time and not achieving goals.
