Why is Circus Arts training becoming so popular? It's an awesome workout that feels more like playtime than exercise. Playgrounds shouldn't just be for little kids! Adults need playtime too! At Upside Aerial Arts & Fitness, we encourage adults of all ages, sizes, and fitness leves to dance, climb, play, and fly! We offer aerial and circus arts classes that build strength and flexibility while providing a fun, creative outlet. We pride ourselves on our welcoming, supportive, non-competitive environment.
