The Perfect Combination
So if high reps promote hypertrophy and low reps facilitate strength increases, then in theory, the marriage of both rep schemes will bring forth muscular and strength development worthy of the Greek gods.
You need to spend dedicated periods of time in both the high-rep and low-rep ranges to maximize your development. High reps build muscle and connective tissue strength, and give your body respite from the grind of low-rep sets, too. Similarly, low-rep sets build neuromuscular and CNS efficiency. When you become more efficient and then go back to your big lifts, you can use even more weight than before, because you're just that much more efficient and effective.
Keep change and move around your workout 💪💪💪.
