My husband John is recovering from both hip and shoulder replacement surgeries within the past 13 months. He is doing great and has had no problems on the bellicon other than a little initial soreness...not related to prior surgeries....which has now completely subsided. I’ve noticed him watching my workout videos as though he might like a little more structure, more variety (and perhaps email encouragements, too) in his rebound workouts. He’ll be pleased to hear that he, like me, has been officially invited to be part of the bellicon family! Thanks!
