Leg Training Study Findings
A new study reveals most people's leg training is unbalanced, focusing too heavily on quads from squats and leg presses while neglecting the back chain. This imbalance can undermine force, balance, and posture — coaches recommend a more holistic approach to leg workouts.
The "posterior chain" refers to the group of muscles on the backside of your body, including the glutes, hamstrings, and lower back. These muscles are crucial for movements like running, jumping, and lifting. A strong posterior chain is essential for generating power and maintaining proper posture. A modern sedentary lifestyle, with prolonged periods of sitting, can lead to weak and underactive posterior chain muscles. This is because sitting keeps these muscles in a lengthened and inactive state. Consequently, when many people do train their legs, they often focus on exercises that they can see in the mirror, further neglecting the back of their bodies. This muscle imbalance, where the quadriceps overpower the hamstrings and glutes, can lead to a host of issues. Common problems include persistent knee pain and lower back pain. The instability caused by weak glutes and hamstrings can also increase the risk of more serious injuries, such as issues with the ACL, PCL, and MCL ligaments in the knee. Correcting this imbalance involves incorporating specific exercises that target the hamstrings and glutes. Deadlifts are highly effective for strengthening the entire posterior chain. Other beneficial exercises include kettlebell swings for explosiveness, glute bridges to target the lower glutes, and Romanian deadlifts to isolate the hamstrings.
