Performing the: A Step-by-Step Tutorial Barbell Bench Press with 1 board
Have a spotter help you lift the barbell from the rack, or if you're confident, lift it off the rack yourself, holding it straight over your chest with your arms fully extended.
Place a one board (a piece of wood, typically 2x6 inches) on your chest. This board will limit how far you lower the barbell, increasing the focus on your triceps.
Lower the barbell slowly until it lightly touches the board on your chest, keeping your elbows at a 90-degree angle and your wrists straight.
Push the barbell back up to the starting position, fully extending your arms but not locking your elbows, and repeat for your desired number of repetitions.
