The Most Critical and Ignored Muscles in Sports Most sports involve a tremendous amount of trunk twisting and hip rotation.
Most sports involve a massive amount of lateral movement.
It is popular to train the quads. It is popular to go for the six pack abs and really work the rectus abdominus. Go the hip section for the charts on these muscles. Because these muscles are so frequently ignored, they can pose a real liability to performance, by slowing lateral movement, causing severe lower back problems, and inhibiting performance in sports involving endurance. Weak muscles most taxed in sports will fail.
