I’m doing the body building template and I’ve read that you recommend going closer to failure for single joint exercises like triceps extensions or biceps curls.
Here’s the thing though: I find it quite unpleasant getting to RPE 8+ on a high rep exercise like biceps curls. Is there any way I could just keep the sets capped at RPE 7 but add in some extra sets to make up for staying further away from failure? Time is not limited.
I don’t think there’s a big difference between RPE 7 and 8 with respect to muscle growth potential on isolation exercises, or even 7 and 9. That said, the small difference is probably additive over time and I would prefer you to do most sets of arm work to failure or near failure. I don’t think doing more volume is likely to make up for this, but you can try it! Let me know how it goes.
As said,The slight difference is probably going to mount up over time, so I’d prefer you to go through most sets of arm exercises until you reach failure or just about fail.
