A sledgehammer slam exercise is a workout that involves using a sledgehammer to strike a tire or other large object repeatedly. The exercise can be performed by holding the sledgehammer with both hands and raising it above your head. Then, you would swing the sledgehammer down and slam it into the tire, using your arms, shoulders, and core muscles to generate force. After the sledgehammer hits the tire, you would quickly pull it back up and repeat the motion. This exercise can be repeated for a certain number of repetitions or for a set amount of time, and can be a great way to build strength and endurance in your upper body. It is important to maintain a strong and stable stance while performing this exercise to avoid losing control of the sledgehammer and to avoid injury.
