The other thing you could think of doing for the client who does not have enough cash for 2-3 sessions per wk, is tiny group training of 2 or 3 ppl. You charge the same as One 30min workout, but if there are 3 in the group, you could train them for 3sessions each. Your still making the same cash per HR, BUT, your clients work out harder each wk, and each wk they get better and better results, giving YOU better testimionals and walking Billboards that tell others how great YOU are. And at a faster rate.
Plus, you might be able to pick up a larger audience who typically cannot afford Sessions??
Something to think about
