Introducing the Stronger Today: 21 Day Challenge.
This isn’t about a complete overhaul. It’s about finding your way back to you.
If you’ve been feeling out of sync – tired, stretched thin, like you’ve fallen to the bottom of your own priority list – this challenge was made for you.
The Stronger Today Challenge is a 21-day reset for women who want to reconnect with their body, build confidence, and feel stronger mentally and physically – without needing to overhaul their entire life or give up the things they love.
This is your place to begin again, gently and powerfully. To find your rhythm. To rediscover the simple joy of showing up for yourself. To build lasting habits that serve you – both mentally & physically. And we're doing it together.
I want to be clear – this 21-day reset isn’t about extremes or quick fixes. It’s about a steady and realistic shift that fits your life and respects where you’re starting from. Maybe your workouts have felt more like a chore than a choice. Maybe you’ve been stuck in a loop of self-doubt or stress that trickles into everything else. Maybe your self-care journey has been on pause in a season of postpartum, busy momming, or career growth. Or maybe you’ve just lost that feeling of confidence and control that used to come naturally. The truth is, life happens – and it’s okay to need a reset. I need a reset too.
Over the course of this challenge, you’ll get a clear, easy-to-follow workout plan that matches your current fitness level and your goals. Every exercise will come with straightforward instructions on sets and reps, so you’re never guessing what to do next. No pressure, just guidance to help you gradually build strength and energy again.
You’ll also have access to specialized tracking tools for your weights and reps. This makes it easy to see your progress in real time without any added stress, helping keep you motivated and accountable to yourself.
One of the most powerful parts of this challenge is the community group chat. It’s a space where you can connect with other women on the same journey, share your wins and struggles, and feel the support that makes pushing through tough days a little easier. You won’t be doing this alone – there’s a circle around you, including me, cheering you on.
So let's do this. Let's find time for ourselves through the busy holiday season, stepping into 2026 feeling our best – together. I absolutely cannot wait & I'll see you on the inside.

Absolutely have loved this challenge! It's been so motivating to have others pushing through the same things as I am and encouraging each other. It was also so helpful having a guideline and a tracker, as a beginner it really helped me to stay on track. I would love to see some core workouts thrown in. Even if it was just one per day's exercise. My mid section has been the most stubborn through this. But overall I am so happy with how this has helped me and I can't wait for the next challenge!

Oh my gosh!!!! I absolutely LOVE this work out challenge. I have fell behind and was so determined to catch up, and did. I know for the next one I need more weights. I workout at home and this has pushed me in all the good ways. I even started using the walking pad everyday. Such a game changer for me. I want to do it now. I have gotten to where I can do 2 miles in around 50 minutes with an 8 pound weighted vest on. HUGE improvement for me. When I started this challenge I wasn’t working out at all. I highly recommend it.

I love that the workouts are simple but effective. I like that there is a timer to time workouts and that you can track your sets and weight used each week. It is an awesome organized app.

I really like the community aspect, I dislike that there are not videos for every single exercise. Coming from someone who is unsure of what I’m doing I thought video would show me exactly what to do. I have been using YouTube if I didn’t know how to preform the exercises but it would just be more convenient if proper form and video was posted for every exercise. I appreciate the home and gym version of each workout plan though.
