You’re a save-the-receipt, closet-renter kind of person, a.k.a. a total commitmentphobe.

Bring that open-market mentality to your fitness routine at Studio Mix, soft opening tomorrow on Van Ness.

Venture upstairs opposite AMC Theatres into the transformed gym: 30,000 square feet with five studios, a three-story climbing wall, and lounge (plus free Wi-Fi), with a cafe (serving organic fare) and kids’ club en route. Decompress in the sauna or steam room, or sign up for a massage from the a la carte service menu.

Founder and industry vet Mystie Webster offers twenty group classes daily, from early morning to late night. Whether you’re into barre, boxing, dance, martial arts, Pilates, studio cycling, or yoga, each is available multiple times a week.

The full schedule launches April 3, but readers can demo one DailyCandy-exclusive class per week until then for free.

You can totally commit to that.

Studio Mix, 1000 Van Ness Avenue, at O’Farrell Street (415-926-6790 or studiomix.com). Memberships start at $85 (discounted from $135) through March 29. DailyCandy classes happen every Wednesday, 6:30 p.m. To sign up, go to mindbodyonline.com.
