HOW: Begin laying on your back with the barbell racked above you with the appropriate amount of weight. As you lay down, your eyes should be directly under the barbell. From here, be sure your feet are flat on the ground, squeeze your shoulder blades together, keep your core engaged, and grab the bar with hands about shoulder-width apart. Bring the barbell over your chest and slowly lower the weight down towards nipple level allowing the elbows to drop down towards the ground. Push the barbell back up to the starting position and perform for the prescribed amount of reps.
FEEL: You should feel your chest and core muscles working as you perform this exercise.
COMPENSATION: Keep your core engaged and feet pressed into the ground. A slight arch in the back is okay but do not overextend with a focus on keeping your core muscles engaged.
