This machine has two uses - for deadlifts as shown in this video and for shrugs. As the deadlift is a compound exercise, it works a lot muscles including the Glutes and Quads (gluteus maximus and quadriceps femoris), hamstrings, trapezius, lats, and erector spinae.
We have added matts to our machine to raise the starting position - always try and touch the matts on every rep.
To start, make sure you have a straight back, squatting into the movement, with the inside of your elbows touching the inside of the legs. Brace the shoulders and lift up thrusting the hips through. Coming down, push the hips back in a hip hinge, bending the knees in a controlled movement.
