Alright challengers… Week 4 is here and we’re leveling up 👊🔥

This one is going to take some planning, some intention… and a little grit.

👉 The challenge: 2 classes in ONE day

No autopilot on this one. You’ve got to look ahead, map out your day, and commit to showing up twice. But that’s where the growth happens.

✔️ Plan your schedule
✔️ Fuel your body
✔️ Show up… again

It’s not just about doing more — it’s about pushing past what’s comfortable and proving to yourself you can.

Double the work. Double the progress.

Let’s see who’s ready to step it up this week 💪
