Hi, I'm Corey-Jay

I'm a natural bodybuilder, and like you, I've lost hours to exercises I found on my feed. Some looked incredible. Most did nothing. So I stopped guessing and started testing.

I put 207 viral exercises through the same test. Only 22 were worth keeping. Pumps Only is the 4-day program I built from those survivors, the one I'd hand a friend who wants results without wasting another session.

What this program helps you do

  • 01

    Stop wasting sets

    Drop the viral moves that look good on camera but do nothing for growth.

  • 02

    Know exactly what to do

    Every session is laid out: exercise, sets and reps. No guessing on the gym floor.

  • 03

    Train 4 days, not 6

    A split that fits a real week, built only from exercises that earn their place.

  • 04

    See why each lift made it

    Every one of the 22 comes with the reason it passed the test.

Still guessing which exercises are worth it?

You don't need more exercises. You need the right ones. Every lift in Pumps Only was tested, scored and earned its place.

Grab the free book and train the 22 that made the cut.

THE TRIAL:
PUMP OR DUMP?

Some were a laugh. Plenty were a DUMP. But some of them were so good they changed how I train a muscle.
