What are some good substitutes for sled pushes?
Ben L., Camden, NJ

One option is to crouch down and push the belt of a turned-off treadmill with your hands. You can also stack weight plates onto a towel and push them across any smooth surface. Lastly, you can do isometric wall pushes. Stand in front of a wall in your socks on a hardwood floor. Extend your arms and begin to drive your legs forward. These three moves all mimic sled pushes and recruit the gluteshamstrings, and lower back.
