Tips

Tucking your elbows towards your body throughout the movement helps to engage the triceps more effectively and minimize stress on your shoulder joints, ensuring a more targeted and safer lift. Maintaining a stable upper arm position prevents momentum from taking over and ensures that your triceps are doing the majority of the work, which is crucial for optimal muscle development. Focus on squeezing your triceps hard at the top of each repetition to maximize muscle fiber recruitment and achieve a stronger contraction. Driving your shoulders into the bench provides a stable base and helps to engage your chest muscles, contributing to overall upper body stability and power during the exercise.
