Now, since the goal of this challenge is to get you stronger, lifting heavy weights is quite inevitable.

Generally speaking, working in the 1-5 rep range (powerlifting range) will lead to increases in maximum strength, which is what we’re after here.

Oppositely, the 6-15 rep range (bodybuilding range) will primarily result in bulk muscle growth and increased strength endurance.

Nevertheless, that doesn’t mean you should totally ditch one of them and instead, you should put most of your focus on the rep range that resonates with your goal, while occasionally doing the other one.
