Answer:
In my Personal opinion my All Muscles need attention ( I do workout), the strongest would have to be chest, shoulders, thigh and your hamstrings. the Muscle that need the most work would be your abs, for some people that have office jobs, drive, or even sit down to eat.
Explanation:
your hip muscles on the front of your upper legs that sit below your abs get tight. Weak abs are a negative side effect of all the sitting as well. When the hip flexors are tight and the abs are weak, your pelvis is going to be pulled into an anterior tilt, or facing downward.
