Check out the new addition to the Lexington Athletic Club weight room, the Rogue Belt Squat. The belt squat is great for deloading the spine when training the lower body.
From the Rogue website:
Benefits of Belt Squats: Performing belt squats rather than traditional back squats / front squats / Zercher squats can be beneficial for a wide range of reasons. Athletes dealing with regular back pain or struggling with spinal compression from axial loading can circumvent those issues by putting the lion’s share of the load on the hips and legs. Similarly, anyone rehabbing from an upper body injury (shoulder, elbow, wrist, hand, etc.) can still get in their lower body work without having to worry about supporting a barbell.
