Impossible Fitness: Workouts, WODs & Training Tools

What is Impossible Fitness?

IMPOSSIBLE Fitness® is a free training library and workout app for people who want to get strong, fit and ready for hard things. It's part of the IMPOSSIBLE family of brands and is built by Joel Runyon's team at Impossible LLC, the same people behind the Impossible List, the 777 Project (seven ultramarathons on seven continents) and years of writing about doing things that look impossible until you do them.

The site is organized around four things:

• Movements: more than 140 exercise tutorials, from the deadlift and pull-up to Turkish get-ups and kettlebell work. Each one covers setup, step-by-step form cues, common mistakes and easier or harder variations, and most include a demo video.
• WODs: the classic CrossFit benchmark workouts, including the Girls WODs like Fran, Cindy, Grace and Helen, and Hero WODs like Murph. Every WOD lists the workout, the standard and scaled versions, and time benchmarks so you know where you stand.
• Tools: free calculators for your one-rep max, training percentages, barbell plate loading, heart-rate zones, running pace and macros.
• Challenge workouts and articles: tests like the 100 burpee challenge, the 300 workout and David Goggins' 4x4x48, plus guides on training, recovery and mindset.

If you'd rather train from your phone, the Impossible Fitness app puts these movements and workouts into guided sessions. It logs your workouts, tracks your personal records and shows your progress over time. It's available on the App Store and Google Play.

Everything here is written for real people training in real gyms, garages and hotel rooms. We explain why a movement matters, how to scale it when you're starting out, and how to progress it once it gets easy. You don't need a coach or a subscription to use the site.

Whether you're learning your first push-up, chasing a sub-3-minute Fran or getting ready for your first Murph, start with the movement library, pick a benchmark WOD and track how you improve. Want to know who's behind it? Read about Impossible Fitness.
