Endless reps aren't going to leave you ripped. You're well into the second phase of Built by Science, so focus on building strength to keep your body growing. By dropping the number of sets and adding weight, you're not only gaining power, but you're also building thick, dense, strong muscle. Push yourself. When the weight starts to feel light, bump it up. You want to grow. You want gains. You need to be challenged.
Pay attention to the differences in tempo. The explosive 2-0-1 for front squats and glute-ham raises differs from the 2-2-1 tempo of standing calf raises, which call for a pause between the eccentric and concentric portions of the movement. Execute a full range of motion, maintain control, and get swole!
