not at all, bb is the worst of the "barbell sports," you'd get much more out of CrossFit, strongman, weightlifting. something with both conditioning and hypertrophy
Wrong on so many levels, actually a pretty foolish statement.
“Bodybuilding” aka resistance training is so much safer than CrossFit or strongman training there is no comparison. If you eliminate the dieting and dehydration for the beauty pageant, the actual style of lifting for hypertrophic effects is something that can be done by people of almost any age (the elderly) and can be done with numerous physical disabilities.
Training a large muscle group for hypertrophy results in an increased caloric burn lasting 72 hours or longer. Cardio can do that, but only early in your training until your body adapts and then the caloric use becomes more centered on the actual time of exercise, and within just a short time of stepping off the treadmill ect, you return to baseline rapidly. Increasing the difficulty becomes difficult quickly and you will be doing marathon length sessions to match the impact of a short session pretty rapidly.
So the problem is increasing the difficulty to challenge your body as you adapt. CrossFit is even worse and the workouts get insane within a short period of time if you wish to have similar results to your earlier training.
Weightlifting is very easy to increase your workout difficulty and challenge your body. You can increase the weight slightly, decrease your rest periods, or do more reps. You can use machines very safely. A 72 year old with a fused spine can train legs (or almost any body part) on machines. And can keep improving and moving up safely.
Every time you train your muscles and get them to trigger an adaptive response, you greatly increase your metabolism for an extended period, as stated 72 hours or more while you recover. As you increase your lean tissue your baseline caloric use increases as well. Combine this with the proven bone density increases and it is a fantastic way for almost anyone to exercise and improve their body composition. You also get cardiovascular benefits if you train with vigor, not as much as a true cardio workout but for some people that is perfect.
