Found footage of my very first Muay Thai fight.

Round 2 got wild… wait for it.

Should I post the full fight? 🥊

I found footage of my very 1st…

WCK Muay Thai fight!
If you think the 1st Round was good, the 2nd Round was CRAZY and the 3rd Round was 🤯...I think you'll like it 🙏🏽😉
I might have some people over for the Carano v. Rousey fight, introduce them to legit carne asada tacos (SD style) and watch the rest of this fight 🥊
Would you come to that party? 🌮🥊😜

Studies show leg and thigh strength are directly correlated with increased lifespan, lower all-cause mortality, and decreased fall risk — especially as we age!

This drill trains:
• Proper squat mechanics
• Explosive power
• Balance & coordination
• Real-world self-defense movement

How it works:
✔️ Squat → stand → hop twice
✔️ Drop back into squat → stand → hop twice
✔️ Transition into a Muay Thai knee
✔️ Reset with a squat and alternate sides

It’s simple, athletic, and brutally effective — whether your goal is longevity, strength, or real-world readiness.

Many strength coaches consider Muay Thai and Western Boxers the most completely conditioned athletes overall.
THIS workout is at the core of a boxer's conditioning... without a punch thrown or taken
Skipping rope like a boxer is a fun full-body workout...
Muay Thai takes it to a whole other level with a weighted rope!
Follow this routine if you've never skipped rope, if you're getting back in shape, or if you want to train like a world champion!

Most people think hip pain is “just age”…
It’s not. It’s lack of movement, tight fascia, imbalance and often old injuries stacking up.

This mobility pattern is what I teach my Muay Thai students, fitness clients, and anyone over 35 who wants to move better, kick higher and harder, and feel pain-free again.

I’ve coached old ladies, Navy SEALs, beginners, and clients with major back/hip injuries for over 20 years — and this simple routine has helped every single one of them.

If your hips feel tight, weak, or painful… try this daily for 2 weeks and let me know the difference!

If any of these movements are painful, (stabbing/shooting), stop and DM me for personalized training (in-person or virtual) that works with your injuries instead of against them, message me “HIP FIX” and I’ll send you the next steps.

Your body deserves to feel strong again.

🥊💪🔥
