Don't know how much credibility, if any at all, I have...but this is just my opinion from reading your log.
1) I would say your squat is high enough based on where your vert is at. Instead of trying to bump up and go for PRs in your squat, keep the high intensity (80+ percent), but with submaximal reps with a fast concentric (So singles with 90 vs 3-5, triples with 85 versus 5-8, 5s with 80 versus 8-10, etc ...so kind of like an MSEM sort of thing and what you have been doing recently). You could cycle them in a 5/3/1 sort of format or just do whatever percentages and reps you'd like. Bump the weights up 5-10 pounds when the weights start to feel like cake. Use Prilepins table for sets and reps. Do some unilaterals and glutehams after to keep your size.
That is one squat workout. Call it monday for example purposes.
2) The other would be your basic dynamic type workout...(speed squats as well as drop and catch jump squats and/or depth jumps) Call this Thursday for example purposes
3) Start jumping more, and like Avishek (I think) said stop doing other plyos. Go in with a plan...about 30 total jumps 3-4 times per week. 3 standing verts isn't going to help anybody, nor is 8 running verts. Over the summer I was squatting consistently 2-3 days a week, but because I didn't have a plan and I was hopping around from scheme to scheme, it didn't improve one bit. This probably works the same way with jumping? I don't know.
Have a high volume session the day before your squat days, and a medium session the day of.
So it could look something like this
Sunday: 4x5 standing verts, 4x5 running/1-to-3 step verts
Monday: "Heavy" lower body from above. 2x5 standing and 2x5 running/1-to-3 step verts before
Tuesday: Upper body, shorter sprints (<50 meters)
Wed: Same as Sunday
Thurs: Dynamic Lower body from above. 2x5 standing and 2x5 running/1-to-3 step verts before
Friday: Upper body, longer sprints (200-400), get shitfaced
Saturday: Recover from hangover
3-4weeks:1week work:deload
The jumps shouldn't take more than 20 minutes, the lifting shouldn't take more than 45. You could even split it AM/PM if youd like (EDIT: and if that were the case do 40 jumps instead of 20 on the squat days). If Jordan Kilagnon can dunk for 3 hours a day, this should be reasonable. If technique is an issue, I know Adam is selling freak technique 3.0 at 90% off for a limited time only
.
Keep it simple. You bust your ass probably more than anybody in this forum, so I'm sure I speak for the rest of the forum when I say it would be great to see you throw down a dunk.
Again, I probably have zero credibility, but that is just my 2 cents so feel free to bash me, call me stupid, naive, whatever. I also realize in have no right to comment on what you are doing since you never really asked for help, but other people were and have been for a while so i figured why not.
Thanks for reading.
