Dan John's 40 days, BJJ, and metabolic conditioning...making sure i do not over train

I have been doing a modified version of Dan John's 40 day program combined with as much skill training as I can muster.

This low volume, high frequency program is good for developing strength while lightly touching on conditioning. I find it a great way to lead into skill training as it warms the body up. I have been performing wave cycling for the loads and will continue to post em as I continue. Currently, I am on the 7th day of the program with a nagging issue with my back, causing me to back off from the deadlift today; however, I feel great with the exception of my back.

The workout consists of

3x3 arch or bench press

3x3 weighted pull ups

4x2 straight or trap bar dead lifts

2x5s hold front lever or hanging leg raises

25-50 KB snatches

followed by 15 minutes of stretching

I have made great progress, allowing myself to arch press 245 for 3x3 fairly easily and pulling 4x2 375 off of the floor extremely well. The back pain is actually from an exercise class I teach on sundays and mondays. This leads me to develop something similar to the cross fit methodology or Pavel's recommendation for athletes

Keep total reps under 10, train skill as often as possible, and do your complimentary work on the days you do not perform strength

The crossfit method of 3 on and 1 off is good, but is not conducive to my lifestyle.

Currently, I am looking at my schedule as follows

P= Power training

C= Conditioning

J= Brazilian Jiu Jitsu

R = Rehabilitation and Recovery

Sunday = R

M = PCJ

T= PJ

W = off

T = PRJ

F = PJ

S= CJ

I will see how this treats my body.
