Last year, for my current clients: It was if they Paid for 20 sessions up front at once and they received 2 FREE sessions (so I could increase Cash Flow & also give something away to current clients). New clients I just had a special where if they signed up for 10 or more training sessions they got a FREE Fitbit/Fitness Tracker & 1 Free session.

I appreciate any ideas that you may have. Thank you!
