I love Dragonfly! I usually do Flow (Hot), and I recently started doing Barre Amped there!
Flow (Hot): Dragonfly really got me into vinyasa. I used to be a strictly Bikram yoga girl, but dragonfly opened me up to a variety of other different poses/stretches in vinyasa! I can see myself improving!
Barre Amped: Oh MAN! Their arm workouts in barre is INTENSE. Definitely thought using 1 pounders was a joke...but it definitely IS NOT. If you do Barre Amped I would grab 2 pounds and 1 pounds, so you can switch off.
Their instructors are great, the studio is always clean, and they're always so welcoming! The Middleton studio is bigger and has an awesome tea room! They're opening up a studio DT soon and I can not wait!
