at a gym

She worked out at the gym three times a week.

I also had a real problem when trying to run or work out at the gym.

The hours he played with the kids, his mind was usually back at the gym.

She said she'd been working out too hard at the gym.

I still see some of those guys at the gym.

But the five hours of practice each week at her gym, she said, are on a different level.

Then we tried to work it off at the gym.

After all, I'm at the gym every day, and girls less than half my age can't keep up with me.

I've been spending a lot of time at the gym.
