Lying Tricep Extension (skullcrusher) Instructions:
Grab a flat bench and an EZ bar. Choose your weight and add it to the EZ bar (if you are new to lying tricep extensions start off with no weight). Grip the bar with palms facing upward and you hands about 8-12 inches apart. Lay back on the bench and extend your arms straight up. Now with your arms straight let the bar drop back slightly so it's not directly over your head. This is your starting position. Bending only at the elbows, lower the weight until it almost touches your forehead and push back up to starting position.
Tips and Safety Advice:
2 Key things to remember with the lying tricep extension. First, you should only bend at your elbows and they must stay tucked in at all times! Really focus on this. Try to keep your elbows pointing at the end of the bench. And second, the start of of the lying tricep extension is not above your head it's slightly back. If you move the bar up this far you are taking the pressure off your triceps and you will not get the full benefit from the exercise.
