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!
