This is becoming my new favorite exercise. Overhead kettlebell walking lunges.

Great full-body exercise.

Why I’ve been training them..

Core strength and stability - Your abs, obliques, and lower back have to work hard to keep you upright.

* Shoulder stability and endurance: Holding the kettlebells overhead strengthens the shoulders and rotator cuff muscles.
* Leg strength: Quads, glutes, and hamstrings are all challenged with every lunge.
* Balance and coordination: Walking while keeping the weights overhead forces your body to stabilize in multiple planes.
* Hip mobility: The deep lunge position helps improve hip flexibility and control.

🏅Athletic performance: This is a great “Fully Loaded Athlete” type movement because it combines strength, stability, and movement quality.

Form tips:

* Lock your elbows out and keep the kettlebells directly over your shoulders.
* Keep your ribs down and brace your core.
* Step into a controlled lunge, lowering until both knees are about 90 degrees.
* Push through the front heel to stand and bring the back leg forward.
* Don’t let the weights drift forward or your lower back arch excessively.

Using two kettlebells overhead while doing walking lunges is one of the best exercises for building total-body strength and resilience because your shoulders, core, and legs are all working at the same time. It’s an excellent addition if your goal is functional athleticism and to become full loaded .athletes 🫡🦾🏁🏁

Dragon flags! The ultimate test for core strength.
___
Got 10 reps?
Think your core is that strong? Want to train for it?

If you can complete the 5 challenge exercises in Level 3 — including 10 consecutive dragon flag reps — you’re on the path. I already have a few Fully Loaded Athletes on my team, but this is only the beginning. 🫡

Every exercise will challenge you, but dragon flags reveal something different. They expose true core strength, control, and total-body tension. That’s exactly why I made them one of the 5 required challenges to earn the title of a Fully Loaded Athlete. .athletes
