What's your training result so far? Can you dunk?
No I can't dunk yet. Here's a summary of my results/progress (probably should have this on the first page):
Started jumping
beginning of 2011 (starting squatting/leg work Dec 2010): <30'' RVJ (never actually tested this initally, but wasn't close to touching 10' rim, could have been lower)
March 2011 (started logging here around then): ~32'' SLRVJ, 29'' SVJ
Sept 2011: ~34'' SLRVJ, 31'' SVJ
Jan 2012: About the same as Sept, getting better at the DSVJ though (~33'')
March 2012: SLRVJ 34-35'', DLRVJ 34'' (big improvement on this over last few months), SVJ 32''
July 2012: SLRVJ/DLRVJ: 37'', DSVJ: 35'', SVJ: 34''
September 2012: SLRVJ/DLRVJ: 37-37.5'', DSVJ: 36'', SVJ 35'' (current PRs)
Overall, gained about ~8-9'' on RVJ, prob 7-8'' on SVJ over 1.75 years, not bad.
Around this time I was jumping quite a lot and I was getting a bit of patellar tendonitis from that and all the squats (and not focusing enough on recovery). So I stopped for a bit and went back to building strength. Squatted heavy 3x/week and put about 15kgs or so on my full squat (can't remember exactly). But the downside to this was I gained a bit of weight (82kgs-->87kgs because I was trying to eat more to keep up with the squat routine) so didn't really gain much relative strength anyway.
Following this, I injured my left knee meniscus probably when playing basketball. Being heavier and probably not being fully recovered from squatting mostly likely contributed looking back on it. Luckily it wasn't that bad, I didn't need surgery or anything, just rested it for a month to be on the safe side, rehabbed it properly and it's seemingly OK now (knock on wood). I've gradually restarted over the last two months, not rushing back (very busy atm as it is with study).
Now I'm going to start squatting more frequently, and eventually get back to jump training with the aim this year of getting back to where I was late last year, then continuing to improve. I think that, to dunk, I was pretty close last year but I never actually was actively trying to dunk at that stage. I thought I would try to continue to build up inches to a consistent 38'', then move into active dunk attempts, but injuries occurred and I always take a very conservative approach in dealing with injuries. I don't mind taking a little longer to do it because I'm not being pressured by time, I've still got a few good years left hopefully, so long as I take care of my body!
