The Bench Press Guide

The bench press is one of the most commonly performed and most poorly executed exercises in strength training. A benchmark movement for developing the chest, triceps, and upper-body strength, it requires precise technique to be both effective and safe. Grip width, bar path, and scapular stability are variables documented by electromyography that directly influence muscle recruitment and injury risk.

This guide details optimal execution technique, the variables that truly influence muscle activation according to scientific research, the most common mistakes, and the main variations of the movement.

Muscles worked during the bench press

The bench press is a compound movement that recruits several muscle groups simultaneously, with varying contributions depending on the muscle portion and phase of the movement.

• Pectoralis major: the primary mover, particularly its sternocostal portion;
• Triceps brachii: heavily involved in elbow extension, especially at the end of the movement;
• Anterior deltoid: contributes to pressing, particularly at the beginning of the movement;
• Scapular stabilizer muscles: stabilize the scapular region and provide a solid base throughout the movement.

Bench press execution technique

Proper technique maximizes muscle recruitment while protecting the shoulder and wrist joints.

• lie on the bench, with your eyes slightly beneath the bar;
• plant your feet firmly on the floor for a stable base;
• retract your shoulder blades before unracking the bar;
• choose a grip slightly wider than shoulder width;
• lower the bar in a controlled manner toward the middle or lower chest;
• avoid bouncing the bar off your rib cage;
• press while keeping your shoulder blades retracted until your arms are fully extended.

Grip width: what the research says

Lehman (2005, Journal of Strength and Conditioning Research) measured the myoelectric activity of the pectoralis major, triceps, and biceps across five bench press variations with different grip widths. The results show that a narrower grip increases triceps activity and decreases activity in the sternoclavicular portion of the pectoralis major compared with a wider grip. The author concludes that, because the variations are relatively modest, grip-width selection should primarily be guided by joint comfort and sport-specific needs rather than the pursuit of precise muscle isolation.

Calatayud et al. (2017, Perceptual and Motor Skills) also examined the effect of grip width (100 %, 150 % and 200 % of biacromial distance) combined with attentional focus on the EMG activity of the pectoralis major and triceps. Their results suggest that an internal focus on the target muscle may slightly increase its activation (4 to 6 %) — supporting the value of mentally focusing on the muscle being worked during execution.

Comparison of bench press variations

The most common bench press mistakes

• Loading too heavy too quickly: compromises technique and increases the risk of shoulder/wrist injury;
• Lifting your glutes off the bench: reduces stability and changes the mechanics of the movement;
• Bouncing the bar off the rib cage: decreases muscular work and increases injury risk;
• Neglecting the warm-up: the shoulders are particularly sensitive without joint preparation;
• Relaxing the shoulder blades during the set: reduces stability and pressing efficiency.

• Creatine : useful for short, intense, repeated efforts such as heavy bench press sets;
• Pre-workout : to consider before demanding sessions requiring focus and energy.

Key takeaways

The bench press remains a fundamental exercise for developing upper-body strength and muscle mass. Grip width moderately influences the distribution of work between the chest and triceps according to electromyographic data, but joint comfort and technical stability remain more important than the search for a universal "optimal" grip.

Mastered technique — retracted shoulder blades, controlled bar path, and consistent progressive overload — combined with suitable nutrition is an effective combination for making lasting progress with this movement. Find all the supplements selected to support your training at Force Addict Pro.
