Targets: Glutes, hamstrings, hips, quadriceps, back
Purpose: Strengthens your posterior chain--the stride-driving muscles in your hamstrings and glutes
Stand with feet beneath a barbell, shins almost touching the bar, feet under hips. Keeping back straight and chest up, sit back into hips and grip the bar. Take a deep breath in and hold it as you push hips forward, keep arms straight, and lift the bar so it travels a vertical path along your body. Do one set of five to 10 reps.
Build On It: Increase weight over time until you reach a max weight you can lift two or three times for one set. Progress to three sets, aiming for five reps, three reps, then one rep of max.
