This exercise is phenomenal for runners as well as laptop users. Yes, laptop users. Too often we are hunched over our laptops with our shoulders rolled forward. Furthermore, it is critical to your running posture to remain upright, with shoulders back and down. When your shoulders are back, your chest is open, allowing you to breath better.
Execution: To perform this exercise properly, think about bringing your shoulder blades together and expanding your chest. Do not focus on lifting the weight.
Notes: Take your time with this exercise. Lower the weight slowly and pause for 2-seconds at the top. Perform 10-15 repetitions.
