When I First Started Training I Made Things Way "Harder" Than They Needed to Be

By James Cerbie

What if there was a proven formula you could follow to consistently hit PRs in strength, power, and endurance?

Add 185 lbs to your deadlift, squat, and bench total: No problem.

Add 3 inches to your vertical jump and broad jump: Yup!

Improve your endurance performance by 30%: Absolutely.

Contrary to what you might think there are plug-and-play templates for reaching these goals.

Repeatable and scalable formulas. They aren’t complicated. But they are hard to find.

My name is James Cerbie and I’m the founder of Rebel Performance.

At Rebel Performance, we venture into the deep trenches of human performance physiology and biomechanics, test 100’s of training iterations every year, and then turn the most effective strategies and templates into detailed step-by-step instructions and case studies for you.

Step 1: We research and test everything

Step 2: You get the best strategies and templates

For example…

Over the years we have stumbled upon a training template that consistently delivers massive PRs across the board. For Keiran, it added 60 lbs to his deadlift, 75 lbs to his squat, 50 lbs to his bench, 3 inches to his vertical and broad jump, and improved his 10 min assault bike challenge by 30%.

And no, that squat graph below isn’t a typo. He couldn’t squat before we started working together because of knee pain.

The best part? You can have the exact templates we used to make it happen and start using them today.

The template isn’t hard. It’s not complicated. All it does is take your effort and intent (which is already there) and funnel it through a fine-tuned system. What is hard is to understand how and why it works.

That’s why we’re here.

Every week we email out tested and proven strategies to get more out of your training.

Just enter your name and email below and I’ll send you the training day templates I mentioned above.
