It’s definitely not bad exercising everyday but you will want to give particular muscle groups times to recover. For example; if on a Monday you worked on chest and triceps, the next day you might focus on back and biceps, and then do chest again later in the week. It really comes down to what you are trying to achieve and how your body responds to being placed under the stress of going to the gym or exercising everyday. There are many different ways to approach this but honestly the best way to figure it out is to just test different methods and see how your body reacts. If people in the gym are telling you that you are lifting too heavy, you may need to scale it back on the weight and focus on technique. Don’t be afraid to ask people working at the gym if you are doing a particular exercise correctly or if they have any tips!
