For those whose backs or builds do not permit weightlifting, a recommended alternative is shoplifting, where the emphasis is not on the weight but on the value of the merchandise lifted.
For instance, if one shoplifts a diamond, it will lead to the lifter being placed in a strict exercise facility where the diet is limited so that weight loss soon follows. Yet, even a 40 carat rare diamond lifted from 47th St or Ramat Gan weighs little and puts no strain on the back or other muscles.
Fencing, an Olympic team sport in which the merchandise is received from one or more lifters and then fenced, and is therefore akin to football in which a ball is received and then thrown or kicked to other players for relocation, is a similarly healthy yet low impact exercise. The EY Olympic fencing champion, a certain gentleman whom I met in his store on Allenby prior to his winning the title, gained said title for receiving jewelry from a lifter and passing it back to the party from whom the lifter had lifted it. Again, no damage done to the back or shoulders but much weight lost by both fence and lifter.
