Well Adam good on you for lacing up the boots for another tilt, 3 months should be enough time to really get your strength levels up, I would use the following approach:
Training Month with Weekly Variation
Program follows the sets and reps and load/intensity protocols as listed, you can follow this for the entire three months, re-assessing your loading at the beginning of each month based around an estimation of your improved 1RM.
Weekly Volume
Week 1 330 reps – Medium/Heavy Load 39%
Week 2 216 reps – Heavy Load 26%
Week 3 222 reps – Medium Load 26%
Week 4 72 reps – Maximal Load 9%
Total for month – 840 reps
This volume only refers to work weights and does not take into consideration the number of sets or reps that would be required to get to the working weight required for the session.
Or as an alternative you can utilise something like this:
If you are unfamiliar with any terms it is bets to google or you tube then as most of them will have a page or 2 dedicated to them, you may like to combine the programs and warm up with one or two of these complex movements before starting the body of the program or you may also like to build your entire workout around these movements and perform maybe 4 in each of 3 workouts a week, utilising a 6 x 3 set/rep scheme
