I used to follow a faulty workout regime that emphasised anterior chain more while stretching the posterior chain more, meaning horrendous posture and muscle strength imbalance. I'm considering yoga to ease the tightness in chest, shoulder and hip flexors. But I'm getting conflicting information about whether yoga will be able to fix the muscle strength imbalance. Information like in order to strengthen back, glutes and hamstring, one has to lift weights and that yoga may not be a good idea for this purpose.
Can anyone shed some light in this regard?
