  • When do I sign up for a class?

    Due to current WA State mandates, our classes must remain small until we can move on to the next Phase. Be sure to sign up for your favorite class ahead of time as they fill up fast. The schedule opens up reservations two weeks in advance so set your calendar reminder to sign up for following week.

  • Getting There

  • Is there parking?

    Yes! Even with the parking lot serving as our workout space, there is still ample parking around the building as well as some spots along 35th. We suggest parking over toward U-Haul and getting a head start on your warm-up (don’t cost nuthin’).

  • Where is the studio?

    We are located on 35th Ave SW, just north of Morgan Street (between Enterprise Car Rental & U-Haul). 

  • Your First Visit

  • What should I wear?

    We are outdoors so be sure to wear sturdy athletic shoes and breathable clothes. You may want to layer up because…..Seattle. Each person is assigned to their own station so you can leave your hat, windbreaker, or what have you, in one spot.

  • Do you have showers?

    We do and they are fabulous! Unfortunately they are not available for use due to the current State mandates. Hopefully we’ll get back to the point where you can use them again, along with the bath towels, shampoo, conditioner and body wash we provided pre-COVID.

  • What should I bring?

    For the outdoor workouts, you need to bring your own mat as well as a water bottle. A small hand towel wouldn’t hurt either for those super sweaty or slightly drizzly days.

    And don’t forget, attitude is everything (insert Grumpy Cat photo). So come with a positive one! We’ve never heard of anyone having much fun with a negative one. Just sayin’.

  • When should I arrive?

    For your first visit, be sure to arrive at least 10 minutes before class. That way you can learn the ropes, grab a spot and hydrate. This is one party where being late is most definitely not fashionable.

  • The Facts

  • What is HIIT?

    HIIT stands for high-intensity interval training. It’s a training technique in which you give all-out, 100% effort through quick, intense bursts of exercise followed by short, sometimes active, recovery periods. This type of training gets and keeps your heart rate up and burns more fat in less time. Who doesn’t want that?

  • Am I going to hurt myself?

    With treadmills, bikes, dumb bells, kettle bells, TRX and other equipment to experiment on, our expert instructors will guide and ensure you are using everything properly.  If you haven’t exercised in a while, there is no shame in pacing yourself during your first class.  We want you to have a great experience, rather than cursing us as you exit.  Lastly, please let our instructors know about any injuries or limitations. They will give you a modification, no problem!

  • Do I have to be a runner?

    Running doesn’t have to be your jam prior to taking our class. No prior experience necessary! There are many ways to create intensity and challenge on treadmills without actually running.

  • Am I going to be the slowest/weakest/lamest person in the class?

    The only competition you’ll find here is with yourself. We’ll guide you through 50 minutes of cardio and strength training that is constantly changing and always challenging, regardless of your fitness level. We’re an all-inclusive kind of place without the buffet lines.

  • I’m allergic to treadmills, is there another option?

    You are in luck! We’ve got two amazing Keiser™ bikes as an alternative to using a treadmill. They are pretty awesome and you can adjust intensity similar to the way you would in a spin class.

  • How often do I need to HIIT to get results?

    Each and every body is different, but we’ve witnessed some pretty incredible transformations when people consistently take 3-4 classes a week for three months or longer. Key word: CONSISTENTLY. On the other hand, don’t be that guy who comes out quick out of gate working out everyday and then burns out just as fast. Those extra pounds didn’t pack on overnight, so it will take time to take them off (and keep them off). Be patient. Be consistent. You will get out of it, what you put in!

  • HIIT & Pregnancy

  • I’m pregnant, can I still come to class?

    First off, congrats!!! And yes, you can come to class but please provide a note with approval from your medical caregiver. Also, please make sure to tell your instructor (we never, ever assume) so they can provide modifications for exercises as needed. Also, walking with incline is always an excellent option if running does not feel good for you and your babe.

  • I just had a baby, is HIIT (high-intensity interval training) right for me?

    We strive to meet all fitness levels, including new mamas. But there are some important things you should know about your postpartum body to help you get the most out of your workouts, prevent injury and build your strength back in a supportive and functional way. Pregnancy takes a toll on your body (duh!) and for your ligaments particularly, it can take months to get them back to their pre-pregnancy state. 

    All this to say, make sure you’ve gotten the green light from your medical provider and please let our instructors know if you’ve had a baby in the last 9-12 months. You’ll still get all the benefits of HIIT training, but it’s wise to start back slow and take options that allow you to move in a way that is effective and safe for building your strength and endurance back (and maybe even better than ever!).
