Single leg deadlifts do a more targeted exercise, when compared to regular deadlifts.
Regular deadlifts are better when trying to gain muscle mass.
Execution
While this is a very effective butt exercise, it is hard to master at the beginning and hard to keep your balance.
You might first try regular one-legged deadlift, and then try this when you master it.
Stand with one leg on the ground and hold dumbbell or dumbbells in your hands. Keep hands straight and place your other foot slightly in front of the other.
Keep your back straight and slowly start to lower your weights toward your foot while bending forward. Push your butt back and keep your leg on the ground straight.
You can slightly bend your leg on the ground while going down, and raise the other foot in the air backwards for better balance.
Keep going downwards with arms straight, until your dumbbells touch the ground.
Come back up slowly, while keeping leg on the ground and arms straight.
When you are back up, straighten yourself.
Muscles this exercise targets
