Exercise generally requires some muscle training. Proper muscle training contributes to the formation of muscles. If the injury is too heavy, it will affect the formation of muscles in the future. When the muscle aches, we should consider letting the muscle group rest and transferring to other muscle groups for training. This will not waste time, but still achieve the purpose of fitness or weight loss. I suggest you eat more egg whites, which is helpful for muscle formation. You can continue to exercise after two days of pain, but I suggest you.
