How do we make sure we’re using the correct weights as we base percentages off of a max that may change during a two or three-month long training block?
If you prioritize your training to focus on generality and volume of work, you will set a better foundation to push the bench press harder and longer and keep it from stagnating.
By varying your exercises strategically not only will you gain strength and muscle faster, but you lay the platform for continued long-term progress over successive phases.
