For women who want to stay strong

Starting over on Monday isn’t a plan.

You want to feel strong, look healthy for the long term, and slow down the clock. What has been hard is finding a way to train that is safe as you get older, and that you can actually stay with.

You are not behind. You do not need to throw yourself into the deep end. You need a clear way to begin, and a reason to keep going.

What do you most want from December 12?

Pick one to see how the session speaks to it.

The woman who can walk you through it is already in your corner. Meet Claire

It is a one-day virtual Mastermind. You will leave with strategies to train safely, mindset tools to stay with it, and the research Claire is there to break down.
Start your included month.
After you join, a short intake helps Claire’s team build personalized workouts, nutrition, and a meal plan for your included month, along with access to virtual coaching.

Exercise involves risk. Participate within your abilities, and stop if something feels wrong. Ask a qualified healthcare professional if you are unsure this is appropriate for you. Fitness guidance is not medical advice. Individual results vary and are not guaranteed.

If you pass this by

You spend another season starting over on Monday, still without a clear, safe way to train as you age. You miss this one Saturday, December 12, at 12pm CST, when Claire is teaching it live. A missed session, and another year of guessing. That is the stake. Not a catastrophe. A Saturday that will not come back.

If you join

You leave knowing how to bring strength training into your life safely. You have mindset tools so motivation is not the only thing holding the plan together, and a month of personalized workouts and virtual coaching to put it into practice. You feel stronger, more at home in your body, and better equipped to stay and look healthy for the long term: to slow down the clock, in the honest, everyday sense.
