We don’t skip leg day here! Before our EMOM we hit the lower body from every angle:

🏋️ Back Squats — building total lower-body strength
🦵 DB Box Step-Ups — single-leg strength, balance & stability
🔥 Calf Raises — because the calves deserve some love too!

Strong legs lead to etter movement. 💥

Creating Balance: Bodyweight lunges + ascending Z-Press sets 🔥

After our upper body pulling session, we balanced the movements out with upper body pressing with Z-Press. Simple movements. Big payoff.

🦵 Bodyweight Lunges — build single-leg strength, balance, coordination, and control.
💪 Ascending Z-Press Sets — challenge shoulder strength, core stability, and posture as the reps climb.

Quality movement first. Then keep building. 📈

☀️ Summer Pump Sessions 💪

This month our strength pieces have been Mini-Pump Sessions like Upper Pull + Lower Pull sessions . We throw in some core work too!

Upper pull work strengthens the back, shoulders, and arms, helping improve posture, pulling strength, and overall upper-body control.

Lower pull work targets the glutes, hamstrings, and posterior chain, building stronger hips, better movement mechanics, and more power for sports and everyday activity.

Strong pulls = stronger, more balanced athletes. 🔥

" JACKIE "

Benchmark month continues !
Today our Teen Fitness Club took on Jackie:

🚣 1000m Row
🏋️ 50 Thrusters
💪 30 Pull-Ups

*Modified as needed

This workout is all about grit, determination, and learning how to push through challenges. The row warms up your grip and gets you breathing. The light weight thrusters stop you from catching your breath, lights up your legs, and saps your grip some more. The final boss is 30 pull ups.

This workout is about grinding it out and working hard. Get work done

Great job, teens! 👏
