I do not recommend working out the same muscle group on consecutive days let alone daily. You need 48 hours of recovery between sessions and as you age 72 hours could be necessary. If you work your chest daily you are eventually going to suffer an overuse injury. Your workout program should have a balanced approach. For example, if you work your chest hard you also must work your back just as hard. If you do not do this, you will overdevelop your chest and have an underdeveloped back. This leads to a rounded shoulder posture with internally rotated shoulders and protracted shoulder blades which can lead to shoulder injuries, headaches, and TMJ issues in your jaw. To balance your rounded shoulder posture you will develop an excessive arch in your lower back leading to lower back pain. An excessive arch in your lower back can cause your femur to internally rotate leading to knee pain. This can then travel lower to cause over pronation of your feet leading to Achilles tendon problems or plantar fasciitis. I bet you never thought that working your chest daily could potentially cause so many problems in other parts of your body did you?
