Every athlete I speak to has tried to lean out at some point.

Most of them hit the same wall..

Energy crashes 🫩

Sessions suffer 😡

Performance drops 📉

So they quit and go back to eating for sport.

But the problem was never the goal. It was the approach.

You can’t cut calories like a bodybuilder when you’re still training and competing like an athlete. Your body will choose performance over aesthetics every single time.

The fix isn’t eating less. It’s eating smarter around your output.

Protect the calories that fuel your work. Create your deficit everywhere else.

You don’t have to choose between looking good and performing well

You just need a strategy built for an athlete.

If you’re lost, HYBRID8 still has spaces available. £120 for 8 weeks of coaching that WILL help you get in shape without sacrificing performance.

Lewis came to me with two goals.

Look better. Perform better across his races.

Most people said pick one.

We did both.

Body transformation ✅
Half marathon PB ✅
5k PB ✅

This is what happens when your training actually has a purpose.

Something is coming Thursday at 6pm for anyone who trains with purpose , whether you’re a runner, Hyrox athlete, footballer or just someone who wants to look good AND perform.
