Skeletal Muscle and Smooth Muscle only

Explanation:

Skeletal is the reason why you're able to walk. Smooth muscle is able to help you digest foods. If he had just eaten breakfast then went for the walk then both of them are being used. Cardiac tissue helps keep your heart going after movements done without control and this is different from the skeletal system because you fully have control.
