Just like any other muscle group, the legs can benefit from higher rep work, but you have to emphasize the heavy weightlifting if you want them to continue to grow over time.
I want to give you a simple leg workout that you can do for the next 8 weeks to see how my advice works for you.
What I want you to do over the next 8 weeks is perform the following leg workout once every 5 – 7 days:
Barbell Back Squat
Warm up and 3 sets of 4 to 6 reps (men) or 8 to 10 reps (women)
Front Squat
3 sets of 4 to 6/8 to 10 reps
Bulgarian Split Squat
3 sets of 4 to 6/8 to 10 reps
Hip Thrust
3 sets of 8 to 10 reps
Standing Calf Raise
3 sets of 8 to 10 reps
Seated Calf Raises
3 sets of 8 to 10 reps
45 Degree Calf Raise
3 sets of 12 to 15 reps
