Pauline:   I joined a gym a few years ago.  I have to say I lost a lot of weight, and I still go now!

Jennifer: That´s great, I'm glad it made a difference!  (ever think) about it before?

Pauline:    Yes, well actually I (have) problems with my health, so I decided to join.

Jennifer:  That was also my situation. I (always hate) the idea of going to the gym until I finally booked in with a personal trainer, now I love it!  I didn't really like my first session, I (train) only for 5 minutes and already I was tired, so I tried to cheat my way out of doing the exercises.  However, my trainer (see) many students like me before, and knew exactly what to do with me! He was a great trainer, but he left 2 years ago so now I have someone else.  It's not easy to change trainers as they have different styles.

Pauline:   He (be) your trainer for long?

Jennifer: He (train) me for 2 years before he left the gym.  He (want) to stay but he had to leave for medical reasons. I (only just get used to) to his style of training when he left, so it has been difficult to adapt again.
