A great combo for the posterior chain: the hamstrings, glutes, and lower back. Start with the GHR. You can use a resistance band to help you complete the movement. Focus on keeping the abs tight to avoid over relying on the lower back. After, move immediately to the sled push. What we're after here is the greatest differential between hip and hands height. Keep those hips high at all times and fully extend at the knee joint on every push. The goal is not to go fast, it's to feel the tension in the hamstring
