Tips To Do Skull Crusher Accurately
Skull crushers have multiple variations that have a lot of similarities. Below are the tips that can be of good help;
- Start with lightweight. This is good for training your arms and reducing elbow pain. Heavier weight might end up affecting elbows.
- Start with a few reps. Doing fewer reps at the beginning is good for training your elbows for future reps. You can increase reps as time goes on when your body is used to the training.
- Remember that it is a ‘skull crusher’ therefore don’t allow it to crush your skull. Control the bar or any weight that you will be using. Lower the bar slowly and grip it actively so that you are in full control.
- Don’t allow your elbows to flare. Your triceps won’t get the full impact of the exercise if you allow the elbows to flare. Flaring elbows take up the workload from the triceps.
- Having a spotter is a good idea. You might need a helping hand that will grab weight in between the sets or when you are done.
- Make sure that you extend elbows when moving weight up and down. Moving upper arms instead of elbows might put unnecessary pressure on your shoulders.
Benefits of skull crushers
Skull crushers are an isolation exercise. An isolation exercise specifically works that particular muscle, unlike other exercises that work multiple muscles at once. They specifically work the triceps. As you move the weight, the impact has to be around the triceps.
