In movies, tv, and in magazines, we are bombarded with images of tall, thin women and muscular men. do you think these images are realistic? do they have a positive or negative effect on society? do you think society associates being thin with being physically fit?

No,

Explanation:

These images aren't realistic because big corporations market there products based on the insecurity of the people buying the product. They have a very big negative effect on society considering there thriving peoples negative self image. Yes i do believe society associates being thin with being physically fit but that doesn't actually mean it is directly related.

take a break move to stretching and slowly work back into physically exercising if the problem continues go to a doctor or physical therapist

well say a good goal is to do 150 sit ups in a week! or 90 pull ups a day. even 60 push ups in a month these are all fair goals!
