So 5 sets of 10 @ 70 should produce some growth yes.
From what we’ve seen in studies and anecdotally, the 65% mark at 10 reps is about 4 RIR. Which means you’re getting about 1 growth stimulating rep per set there.
At 70% you’re looking at maybe 3 RIR, so 2 growth stimulating reps there.
If you’re doing 5 sets like that, you’re getting around 10 growth stimulating reps.
Or…you could do 2 sets of 6 reps to failure and get basically the same amount of stimulus.
