Thanks for the idea on using the bar and leaning slightly into the rack supports for stability for calf raises. I found on the second set I was pretty much able to stabilize myself. It’s working out perfect with no back problems just holding the bar like I was at the top of a deadlift. I started at 210lb since that’s what I would have been what I was deadlifting today and 2x20reps was easy. I just used 2 25lb plates to gain a little extension on the calf raises.
