If you have severe bone thinning/weakness, I would recommend being evaluated by a physical therapist to help guide safe exercises and give your restrictions on how much weight you can safely lift.
Xa amathambo akho ecutheka/ebuthathaka ndikucebisa ukuba uxilongwe ngugqirha oyingcali ukuze akuncede ngesikhokelo semithambo ekhuselekileyo aze akumisele ubunzima bezinto omawuziphakamise xa usenza imithambo.
