i agree with MID theres nothing you can't do in your living room that can be done in a gym, i had a personal trainer (at my gym) and the best work was done with core exercises on a mat with a few simple weights, if going to the gym inspires you to work out great, but a PT inside or outside the gym was essential for me, or a buddy to train with I'm sure would be good too, when i was on my own it was too easy to do less work and head for the showers, don't be discouraged from doing the exercise/gym it starts off very hard but quickly gets easier, the PT also gives you a personalised training plan tailored to your fitness level and ability (in my case there was neither a fitness level or ability) mine was £40 an hour once a week but you could maybe have them twice a month even if its just in the beginning to learn to use the equipment properly so you don't hurt yourself
