** Just about every muscle of your body will get trained with this movement.
Using Bands with Pin Pulls is a great way to get extra work out of the glutes. The trick is to make sure you have band tension while the bar is still on the pins. To do this you may have to double or triple loop the bands around the rack (Note: Make sure rack is bolted or weighted down). As you pull the bar off the pins the band tension increases.
The main thing to remember with all pin pulls is to try and get in the same body position you would be in with a regular dead lift at the same angle. To many times lifters step too far off the bar when they should be right up on it.
Also, do not make this a leg pressing lift. Keep your head up and PULL the bar with you upperback and glutes. Think of this as a hinge with your body.
This is max effort at its best. Work up heavy for 1-3 reps with 7-10% jumps as you work up.
