HIIT Lab

HIIT Lab Feeling intimidated? No need to worry, you choose your weights, set your pace and work to your person Test your superpowers during HIIT Lab’s 60-minute workout.

You’ll run, squat, jog, lift, cycle and maybe even dance a little, all while strengthening your heart, burning tons of calories and building muscle. Our class of up to 20 people begins with half of the class killing it on one of our fierce Woodway™ Treadmills or Wattbikes™, while the other half is rockin’ some strength training. Then we switch it up. To finish up, we always end each class with som

e well-deserved stretching. Each class promises to be unique and fun, featuring energetic instructors and upbeat music. All you have to do is work hard and clear your head, even if for just one hour.

Unless you’ve been quarantined with Hantavirus (too soon?), you’re probably seen tons of soccer related stuff all over Seattle. So we’re jumping on the bandwagon with a new challenge in a match pitting the Central District vs. West Seattle. Details are above as well as in-studio. Apparently every phrase and logo has been trademarked and copyrighted so get ready for HIIT Lab’s version of the GLOBAL GOBLET CHAMPIONSHIP!🏆 Sign up with the link in our bio!

As Mental Health Awareness Month comes to a close, we want to remind our community that caring for your mind is not limited to one month on the calendar.

Movement is about so much more than physical strength. It’s about creating space to breathe, reset, reconnect, and simply be.
Whether you walk through our doors for the workout, the energy, the community, or a moment for yourself — know that it matters.

We encourage you to continue prioritizing your mental well-being in whatever ways serve you best 😌

Regular human 👉🏼Relieved to run at 0.0 incline.
Tristan ⏩ Sets his incline to 25.0.

Regular human 👉🏼Signs up for a stair climb run.
Tristan ⏩ Wins Base to Space. Multiple times.

Regular human 👉🏼Drops off kid at school, goes to work.
Tristan ⏩ Drops off kids at school, goes to work with more kids 🧑🏽‍🏫

He’s up when most of us are still asleep — often getting in a warm-up run before stepping foot in the studio. So at 5am, Tristan does seem intimidatingly superhuman but if you get a chance to chat with him, you’ll learn he’s one of the nicest humans around. A man of few words, his actions speak volumes. More than the monster inclines, it’s his consistency that is most impressive. Thanks for continuing to show up again and again! The rest of us may not win Base to Space (okayyy, none of us will😆) but we can all keep showing up 🚀
