My legs have always stayed more built, stronger, and kept their size when I get at least two leg sessions in a week.
I focus one being on strength and improving my numbers in the Squat.
Barbell Squat is always the first exercise in this workout.
The second workout, which is 3 days later, is Hypertrophy based. The squat is still there but for very higher reps and never first in the workout.
Here is a couple routines of those two days:
Day 1: Lower Body Power
Squat: 4 warm up sets. 1 set at 90% of max. reduce weight to 80% and perform 5 sets of 3
Leg Press: 4 sets of 12, 10, 8, 8 (pyramiding up)
Bulgarian Split Squats: (pausing at the bottom with 2 seconds each rep) 4 sets of 8
Stiff Legged Deadlifts: 4 sets of 10 (straight sets here about 2 reps shy of failure)
Glute Ham Raise: 4 sets of 10 (pausing at the top flexing hard)
Day 2: Hypertrophy Day
Hack Squats: 3 warm up sets. 4 sets of 15 , 12, 10, 10 (do two drop sets on final set)
Barbell Squats: 4 sets of 12 at 65% of max
Single Leg Leg Press – 4 sets of 15
with 185 on back – 8 steps total. 3 sets
Lying leg curl – 4 sets of 12 (2 drop sets on final set)
Single leg leg curl – 4 sets of 15 (pausing at contraction)
There you go.
I switch the exercises and order constantly but the basics of Power and Size and the rep ranges often stay the same.
If you haven’t gone to twice a week leg training I recommend it, watch you get leaner, appetite increase, and your legs grow!
Train on.
