Before you buy

How do I access the program after buying?

Pay once through Stripe, then create your Hybrid Fit Mom account using the same email you paid with. If you already have an account, sign in. Your sessions, exercise videos and eating guide are in the online member area, with progress saved across devices.

Is anything shipped to me?

This is a digital training program. You access it online through your account. No physical product is shipped, and kettlebells and other training equipment are not included.

Is this for beginners?

Yes, if you can pick up a kettlebell and hinge with a flat back. The first two weeks are deadlifts, swings, goblet squats and strict presses, and nothing in them is fast. The flow at the end is advanced, and that is the point: by the time you reach it you will have trained every piece of it for five weeks.

What equipment do I need?

One kettlebell. Mari demos a few movements with two, and the notes say so, but the program is written for one. Pick a weight you could deadlift for ten clean reps; the program tells you when to go up a bell.

What if I miss a session?

Do it next. The program is twenty-four sessions in order, not twenty-four dates. Each one has a button that marks it done, and the next one waits for you.

Is there a refund?

Fourteen days. Train it, and if it isn't for you, email Mari at hello@hybridfitmom.com and she'll refund you in full.
