THE EXPERIMENT

Why 9 out of 10 viral gym exercises didn't make the cut… and the 22 that will change how you train

Hey, I'm Corey-Jay Eyndhoven.

Over the last several months, I ran a ridiculous experiment: I tested 207 of the most viral gym exercises on TikTok and Instagram.

If an influencer claimed an exercise was a "game changer", I tried it on camera.

And you know what I found? Most of it didn't hold up.

Out of 207 exercises tested (with over 281 million views on the tests):

  • 185 didn't make the cut. Awkward, overhyped, or just not worth your sets.
  • Only 22 made the cut as game-changing PUMPS.

Instead of leaving those 22 scattered across hundreds of posts, I put them into one structured 4-day upper/lower split.

I call it PUMPS ONLY.

Inside this 4-week playbook, you'll discover:

  • 01

    The 4-day upper/lower split

    50–60 minute workouts built for muscle growth, with 3 rest days a week.

  • 02

    A link to every video test

    Tap any exercise in the PDF to watch the original test before your first set, so you nail the form.

  • 03

    The 4-week progression

    From Week 1 "Test It" to Week 4 "Send It", with exactly what to add each week.

  • 04

    Built-in workout logs

    Screenshot or print them and track every working set.

  • 05
