Do not forget to perform single leg exercises. They should form a large component of your workout program. In terms of my own workouts, at least 50% (if not more) of my lower body exercises are unilateral. Of course this percentage will vary on an individual basis.
Some of my favourite single leg exercises include:
1. Reverse lunges
2. Rear foot elevated split squats
3. Pistol squats
5. Single leg RDL's
6. Single leg TRX hamstring curls
7. Single leg hip thrusts
8. Single leg glute bridge with single leg lowering (or abduction).
As you can see, I perform single leg exercises that train the squatting, hinging, and lunging movement patterns. While performing heavier bilateral exercises like squats, deadlifts, and hip thrusts are awesome, single leg exercises are extremely important and should be an integral part of your workout program as they will help improve your overall performance, health, and ability to gain muscle.
