I may be starting a new job in a gym near me and I was wondering if anyone here with sales experience is well read enough to recommend a few good books on the subject. It's not so much "cold calling" type selling (although I can do that if I wish) mostly because I will have new people coming in for fitness assessments and buying orientations and fitness programs designed by me, but I need to learn to sell people on larger programs and even maybe try to sell people in the gym on renewing for more sessions. I don't have to sell memberships thank god, so they are there to train.

I've never worked a job where I've relied on almost all commission and and need to figure out how to go about the process of getting names signed on the dotted line. I'd prefer some ebooks if they are available to read on my tablet while riding the train if possible.
