Summer group fitness schedule is officially here! We just wrapped up our last Tuesday night strength + Conditioning and will have Thursday night Rizzmic this week only… but Friday morning restorative yoga starts THIS WEEK!!! While it pains us to break it to those bad asses that showed up tonight, it was awesome to hear all about their upcoming trips and reassure them that end of August we will boost our evenings again!!! Who is ready to enjoy more of those sunny evenings here in the beautiful PNW?!
☀️
Even with the sunshine on the way (after this next week of rain) you better keep planning those trips into the gym. Get into those early classes so you have more of your evenings free!!! Even with all that being said we will still have all of our other evening classes ready to kick yalls booties, like Monday/Wednesday barre at 5:45pm 😉 happy sweating yall and I can’t wait to see you tomorrow!!!
