There is no magical sets/reps scheme when trying to build strength. Too many people fall in love with sets/reps schemes whereas in reality it doesn’t really matter provided that:
- You do your assistance work for strength at 75-80% or more
- Train hard on all your work sets
- Perform a total of 20-25 reps
3/2/1 3/2/1 3/2/1
2 reps EMOM for 10-12min with 80-85%
I would pick one, do it hard for 3 weeks than pick another one.
