Skull crushers are super important for building strong triceps, but you’ve got to pay attention to how you do them. These exercises really target your triceps and can help your arms get bigger and stronger. If you want to get better at skull crushers, keep reading.

Doing skull crushers isn’t just about lifting heavy weights; it’s about doing the moves right to stay safe and get the most out of them. Just like with bench pressing, you’ve got to make sure you’re doing it with good form to avoid hurting yourself and to see better results. Start by making sure your core muscles are tight and your body is in a good position on the bench before you start. This helps you stay stable and in control while you’re lifting. Also, keep your feet planted firmly on the ground, about shoulder-width apart. Push through your heels as you lift to stay steady and give your muscles more power.

When you’re doing skull crushers, straighten your arms out all the way while squeezing your triceps at the same time. Try to lower the barbell down towards your forehead while keeping your body in the right position. Don’t arch your back too much or make any unnecessary movements that could lead to injuries. Skull crushers can be tough on your body, and they might make the rest of your workout harder. One thing you can do to help is to wear elbow sleeves to reduce any discomfort and to keep your elbows in line. Friction from the barbell can sometimes cause discomfort, which can slow down your progress.
