How to do Barbell Bench Press (knees at 90 degrees)

01
Setup
Lie on a flat bench with your eyes directly under the barbell. Position your feet flat on the floor, about shoulder-width apart, with your knees bent at a 90-degree angle.
02
Setup
Grip the barbell slightly wider than shoulder-width apart with an overhand grip, ensuring your wrists are straight and elbows are slightly tucked. Unrack the barbell, holding it directly over your chest with arms fully extended.
03
Inhale deeply and slowly lower the barbell towards your mid-chest, keeping your elbows tracking slightly inward, until the bar lightly touches your chest. Maintain control throughout the descent.
04
Exhale as you powerfully press the barbell straight back up to the starting position, extending your arms fully but without locking your elbows. Focus on driving through your chest and triceps.
05
Keep your shoulder blades retracted and pressed into the bench throughout the movement to maintain stability and protect your shoulders. Complete your desired repetitions before safely re-racking the bar.

Tips

Maintain a slight arch in your lower back, keeping your glutes and upper back firmly pressed into the bench to create a stable base and maximize power transfer.
Control the eccentric (lowering) phase of the lift; don't let gravity do the work, as a controlled descent builds strength and reduces injury risk.
Focus on pushing the barbell slightly back towards your rack position as you press up, rather than straight up, to engage your chest more effectively.
Actively drive your feet into the floor throughout the lift, using leg drive to assist in pushing the weight up and enhance overall stability.

Common mistakes

Flaring elbows out wide puts excessive stress on the shoulder joints; keep your elbows tucked at about a 45-degree angle to your torso to protect your shoulders and better engage your chest.
Bouncing the bar off your chest uses momentum instead of muscle, so ensure a controlled descent and a brief pause at the bottom to maximize muscle activation.
Losing lower back contact with the bench reduces stability and can lead to lower back strain; actively drive your feet into the floor and keep your glutes engaged to maintain a strong arch.
