First of all, let me introduce some sports about leg workout to you. 

The first one,Dumbbell Sumo Squat.How to: Start standing with feet slightly wider than hip-width apart, toes pointed out at 45 degrees, torso slightly forward, holding a dumbbell with both hands in front of you. Inhale, bend knees and sink hips down until thighs are parallel to the floor. Exhale and drive through heels to return to your starting position. That’s one rep. 

Secondly, Dumbbell Suitcase Deadlift.

How to: Hold a dumbbell with left hand, feet shoulder-width apart and right hand clenched in fist, arm extended out to side. This is your start position. Engage abs and keep knees soft, then sit hips back to slowly lower weight until it reaches middle of left shin. Back should be flat and parallel to the floor. Press through heels and contract core to quickly return to start. Squeeze glutes once completely upright. That's one rep.
