1. Wide squats- stick with low rep heavy weights. Lets go with 5-8 rep range and make sure your feet stance is wider than your shoulders. When you get to the bottom of the rep, hold for 2 seconds there.
2. Sumo – dead lifts with barbell, use same steps as with wide barbell squats
3. Barbell forward lunges, if your knees are good then wrap them and do heavy reps of 5 3-5 sets, and I would follow up with high rep light weight to finish your workout.
If you do just these 3 workouts, with heavy weight, at some point and time you’ll have the booty you dreamed.
