Joined a fitness club

[rebbonk]

'I feel like my body has gotten totally out of shape, so I got my doctor's permission to join a fitness club and start exercising.

I decided to take an aerobics class for pensioners.

I bent, twisted, gyrated, jumped up and down, and perspired for an hour.

Spoiler:

By the time I got my leotard on, the class was over.'
