Do push-ups and sit-ups every day until you can't move. Two months, T type+muscle

S-shape I think your shoulders are not wide enough, your waist muscles are underdeveloped, your waist is not straight, and your hips may be a little big.

Shoulder width is push-ups, and pull-ups are also acceptable.

Running only the waist muscles, running fast should be better.

Don't sit for a long time, walk more. Sedentary will make hip fat accumulate.
