Hi Coach - I underwent a micro-discectomy for a severely herniated L5/S1 about 5 weeks ago. Prior to the herniation I followed a more powerlifting centered routine with the occasional (2-3 times a week) crossfit workout for conditioning and volume. Post herniation I have put powerlifting on hold and am doing body weight exercises (basic pull ups, push ups..etc) to keep myself sane until I can get back to the gym. I recently also purchased an Airdyne as it has always been an intense low impact full body exercise for me.
My question to you is whether you have ever seen someone preserve muscle mass while using an Airdyne exclusively. Obviously it isn't best case scenario but given the circumstance I am trying to keep busy while my back heals. Do you have any advice on approaches (HIIT / steady state...etc) to maximize muscle preservation here?
