How to Train legs to failure using "post-exhaust training"

In this video, we learn how to train legs to avoid failure using post exhaust training. First you will do a hack squat, which is where you will hold dumbbells and place your heels on a step, then squat down through the heels. Keep your chest up while doing this and you will work your butt, hamstrings and lower back. The next exercise you can do is a front lunge, which includes you lunging to make a 90 degree angle alternating between legs. The last exercise you can do is to hold a bar and squat down, tapping your butt down on a folding chair. These can help build the strength in your legs and tone them much more!
