Okay guys, I've pretty much been doing low rep exercises for quite some time now doing between 3-5 sets each... I switch up my workout on exercises only, but usually keep the same basic principle of low rep (6-8) and 3-5 sets. It's worked great for quite some time but now I think I've hit a plateau I've changed my diet, gained a little weight, but again, I'm stuck. I was thinking of using high rep for a week or two and wondered how you guys go about doing it... Do you use the same exercises you've been doing and start using 12-15 reps? Do you change the sets at all? Or a completely different workout? And how long should I do it for? I love hitting white muscle fibers but I believe I need to change it to lighter weights for a little bit as I am feeling more tired as of late and believe I may be overtrainining slightly.
