Many people says that doing more reps with less weight will help you increase your muscles but one of my friend thinks it the other way... Whuch one should I follow???
Scroll down a little until you see the chart. Hope that helps!
Well, my thought here is that more reps with lighter weights is better for you. Just seems healthier, and I bet you build muscle faster that way too. I personally don't know much about weightlifting though.
If you goal is muscular hypertrophy. It doesn't matter what reps you do. The last 2 reps til failure is where muscle activity is off the charts. So it's just using heavier weights you acheieve this quicker with less reps than lighter weights. That's all it is. If you are new to weight training though, I will say stick to higher reps. Get your body use to the movements and it's good to practice more on form in the beginning.
