Hmmm. I can see where he is coming from, but its not quite all it could be. Again, I dont hate it, I just dont love it. If it were my daughter's boyfriend I would be OK with him coming to the house, but if he asked for her hand in marriage, I would refuse- that make sense?
The main problem is that he approaching strength training with a bodybuilders mindset- the volume is too high, and there is not enough complimentary work for the basic lifts.
Also, this 'you cant train for more than 2 weeks' thing- I dont know where he got it from, but he is wrong. Strength training has been shown to strengthen, not weaken, tendons and joint function.
Here Is what i would prescribe based on you wanting to train 4 days a week (if that is a number he came up with, and you want to do less/more days per week, then let me know)
Back extensions (weighted) 5x5
Hamstring curl 5x5 (if you had a glute/ham raise, then that would be ideal, but most mainstream gyms wont touch them)
Chins 5x5 (any grip. weighted if necessary)
Workout 4.- (a) and (b). Alternate each week.
Box Jumps x5
Plyo push ups x5
Hip Pop-ups or full bridges if possible x5
Hang clean and press 5x10
Hanging leg raise x5
Weighted twists (hold a plate) on 45 degree sit up bench 5x10
there you go, she can marry that one, he's a keeper
