Old School Tricep Secrets from Westside Barbell
January 25, 2026In this video I break down two legendary tricep movements that built some of the strongest bench pressers on the planet: the guillotine press and the JM press.
A lot of lifters have heard of the JM press, but very few truly understand how to perform it correctly. Even fewer know about the guillotine extension, a brutal movement I learned firsthand at Westside Barbell from Louie Simmons.
I explain how chains, bands, reverse bands, and tools like the Slingshot change resistance, protect your joints, and teach you to move explosively. You’ll see exactly how accommodating resistance makes the bottom lighter and the top heavier, and why that’s perfect for tricep development.
I also tell the story of JM Blakley, one of the most explosive bench pressers ever, how he trained, how he ate, and how this unique pressing style became legendary.
Most importantly, I show you how these exercises should FEEL, not just how they should look. At the end of the day, if your triceps are getting crushed and your elbows feel good, you’re doing it right.
Try these movements, experiment with different bars and setups, and find what blows your arms up the best.
Strength is never weakness. Weakness never strength.
