Use your BRAINS to build your BRAWN

I've been doing it wrong all this time!

Lol. It depends on what you want. “Bro science” says to get big muscles and or get big strength- lift big weights. For strength training- you generally do want to lift the heaviest weights you can get minimum reps on for your full sets. BUT- lifting “lighter” weights for more reps can build endurance, still builds strength, generally builds size a little better, and what’s really important isn’t how “big” the weight is, it’s to keep increasing the weight gradually at a metered pace, or to keep increasing the reps or intensity. Some people would rather bench 400lbs for 5 reps and some would rather bench 200 for 12 reps. Whatever you can do and gets you the results you want.
