I think you will fit nicely into my Fitness and Weight Loss Program. The workouts in this program start off easy enough and if you are fit you might want to jump up to workout 13 or 14 in the plan and start there or you could head over to the Workout hub and pick any of the tough Hiit classes there. You'll also love the Live classes that I add to this program every Friday.
I have two payment options for my Fitness and Weight Loss plan. You can subscribe for €6 per week, which you can cancel at any time, or you can get a better deal of €54.99 for three months (non-refundable).
