Top 4 Corrective Exercises

I've been reading lots of lists lately where trainers (by the way, I just passed my certification recently) list their favorite exercises for correcting posture, stability, mobility, and muscle problems. So I thought I'd jump in with my own list of top corrective exercises.

1. Kettlebell Swing-This corrects a lot of hamstring and hip extension problems by balancing the muscles that we use. Many times we use only our quads and ignore hamstrings/glutes/hip flexors (runners especially).
2. Single-Leg Romanian Deadlift-You must start this without weight and add weight as you get the hang of it. This also works hamstrings/glutes/hip flexors but it does it while working on balance at the same time.
3. External and Internal Shoulder Rotations (or Shoulder W's)-Most men have internally rotated shoulders because we have only worked our chest and shoulder muscles. These exercises help restore balance and condition the rotator cuff muscles and middle trapezius.
4. Turkish Get-up-I'm just now working on this exercise, but it focuses on stability and mobility throughout the body while moving from lying down to standing up and back.

Here's a link to an ACE Journal article on corrective stretches and exercises.
