We all know how difficult hot yoga workouts can be (who hasn’t seen the “Yoga Mat for Sale, Used Once” Craigslist ad by this point?), but this place takes it to a whole new level. Arrichion’s newest class, called MMA hot yoga, incorporates 3-pound weights into the workout. We’re talking squats, lunges, planks, punches and kicks … in a 95-degree room. Talk about sweating it out. If the hot room isn’t for you, check out Arrichion’s free yoga at Oak Room once a month. It’s called Stretch+Sip for a very good reason: drink specials afterward at All American Pub. Yoga and drinking? Gets our vote.
