Is it safe to do boxing,swimming and weight lifting at the same time?
You asked, “Is it safe to do boxing,swimming and weight lifting at the same time?” NO! IT IS NEVER OK TO LIFT WEIGHTS WHILE YOU ARE SWIMMING! It is, per your question, OK to box and swim at the same time. But, if you lift weights while your swimming you’ll sink and drown and the weights will rust thus polluting the pool. Then there is all of that mess of your weighted down body (you were holding the weights) on the bottom of the pool and the bloating that occurs as bacteria inside of your body causes you decay thus making gases that cause the bloating. Then, sooner or later your body parts start to fall off and it will really detract from the pool. Most people will not come back to the pool for swimming and it is likely that during swim meets many swimmers will not want to use the lane in which your body is rotting. Sooner or later, flesh falls off and floats around the pool and swimmers would be colliding with the flesh. You’d be a MESS! So, in summary, I’d suggest that you don’t lift
