Does lifting heavy weights lead to poor posture?

Answer 1

Exercises that train your abdominals and back are very good for your posture.

- Latissimus Dorsi

- Abs

- Posterior Deltoids

- Trapezius

- Rhomboids

- Spinal Erectors.

Machinese that train those muscles are seated rows, or lateral pulldowns.

avoid machines that train your pecs. such as a benchpress.

Answer 2

If you don't balance your workouts, then yes. You can get poor posture if you only work your chest, core and biceps. If you neglect your traps, upper back and your lower back, you will get muscle imbalances which will lead to some ugly postures. To fix this, add more back training to your routines and start stretching more.
