Crunch Fitness Tallahassee on Instagram: "On the seventh day of Fitmas Santa trained with me… 7 JINGLE BELL JACKS! 🔔✨⁣ ⁣ Jumping Jacks are a total-body warmup that increase circulation, elevate heart rate, and boost coordination. They activate your legs, shoulders, core, and stabilizers — making them the perfect move to get Santa warmed up before the busiest night of the year. Great for improving endurance and agility.⁣ ⁣ Mix it up with power jacks, step-out jacks, or plank jacks. Tag us in you
