Thanks for your question. Many of us don’t like to warm up in the gym. I also don’t like to warm up in the gym when I am new at the gym. But warm up is an essential part in the gym. We should not ignore it. Warming up means to do some basic workouts like running,cycling in the gym. The main benefit of warm up is injury prevention.Warm up help our body to be ready for our workout .When we do warm up our blood will be pumping to an area and lower the chance of a muscle pull or joint injury. It also has positive effects on our body because after a warm up our strength and focus should be peaked. It also brings mental and physical peace and makes us ready to do our workout without injuries. So,we should do our warm up  in the gym. Hope you find your answer.
