Some people's joints articulate in a manner that allows them to benefit greatly from squats; others may not benefit at all. If you're not too tall and have short limbs, it may be the best exercise for you, but if you're tall with long legs, it might be both ineffective and dangerous.I was stubbornly faithful to squats for years until I finally realized they were not well-suited for my body structure. After I switched tomore muscle-intensive movements, my gains in leg size were astounding.
