If you train the same muscle groups every day youâre not giving the body enough time to recover fully, which can significantly slow down your progress and increases the risk of injury. In theory, you could lift weights every day as long as youâre not training the same muscle groups on consecutive days. Ideally youâd take at least one or two days of rest per week to allow your body to recover, which is why most lifters will take the weekend off.
