Show answer and explanations
Answer
D
NASM Phase 3 (Muscular Development) uses about 75–85% 1RM for 6–12 reps, heavy enough to drive hypertrophy with moderate-to-high volume.
A
50–70% 1RM is the Phase 1 stabilization-endurance range; it is too light for the hypertrophy emphasis of Phase 3.
B
85–100% 1RM belongs to Phase 4 maximal strength with 1–5 reps, not the 6–12-rep hypertrophy work of Phase 3.
C
30–45% 1RM is the load NASM uses for the power exercise in Phase 5 supersets, chosen for speed rather than muscle growth.
D
NASM Phase 3 (Muscular Development) uses about 75–85% 1RM for 6–12 reps, heavy enough to drive hypertrophy with moderate-to-high volume.
