Also asked, does your rib cage expand when you gain weight?
It's good to note any abdominal fat can cause your rib cage to expand. Now if you're a male(this applies to female but, it's pretty rare unless they go super body-building), your rib cage can expand if you do lots of weight lifting. ie. Building muscles to point you get the classic “v-shape” body.
Secondly, can your rib cage expand? YOUR RIBS MOVE LIKE A BUCKET HANDLE. The ribs allow chest expansion for breathing, Martinez explains.
Also asked, does rib cage get bigger with age?
A slight increase in rib cage size is observed from age 20 to 30, but rib cage size appears fairly constant for ages 30–100. There are also visible shape changes that occur with age, particularly for the angle of the ribs relative to the spine and the kyphosis of the spine.
Can your rib cage change shape?
The rib cage becomes rounder, and the angle of the ribs relative to the spine becomes more horizontal. Changes in the size and shape of each of the 24 ribs also occur, as was seen in a 2014 study, which examined CT scans of 339 people across the age span (birth to 100 years).
