Our classes are set to the beat of the music resulting in a workout experience to remember. Feel the energy as you vibe together in a group workout that motivates you to pulse a little bit longer, squat a little bit deeper + elevate for the full duration.Whether it’s Barre, Core Pilates, Sculpt or Reformer Pilates, prepare to work body and mind, as you enjoy receiving detailed attention to your form, alignment, technique + breath.Enjoy that uptempo choreography + the serotonin-boosting vibes of your raising heart rate as you move through an empowering, well-balanced 50 minute S191 workout.

We also LOVE a themed workout so get ready to see ABBA, Taylor Swift + Beyoncé on the schedule. Our S191 workouts also include a lot of props - from Bala wrist/ankle bangles + weighted power rings to Balanced Body Pilates circles to booty bands, core sliders, dumbbells, medicine balls, jump boards + more. We bring extra challenge + support through our props, ensuring every workout is accessible, fresh, effective + independently-designed by our incredible instructors. You’ll be in the greatest of hands as your mood rises high + that booty gets down low. Don’t believe us? Come give it a try. OUR CLASS SCHEDULE With maximum flexibility in mind - we have cultivated a pretty huge class schedule with lots of daily classes to make life easier by making workouts available in as many hours of the day as possible. That’s 7 days per week of classes from sunrise till way after sunset. We do recommend that you book your spot online in advance - but you can always take a chance by walking into the studio (we cannot guarantee there will be a space but you’re welcome to try anytime) + our host can check if there’s a spot free. Looking for S191 to be part of your daily or weekly life? We offer several memberships + class card to suit your needs + we only want you to pay for what you use. This is why our memberships allow you to “roll over” any classes that you don’t use. Our dedicated team are online + in the studios 7 days per week to assist you with booking classes, selecting the best membership + beyond. OUR LOCATIONS Studio 191 can be found in Amsterdam’s de Pijp, West + Oost neighborhoods. Our West location offers showers + large changing facilities, as well as a dedicated Reformer studio. Our de Pijp + Oost locations are ‘express studios’ - whilst they still have lockers, water fountains + changing facilities, they do not have showers. All of our studios have local bike parking facilities + can easily be reached by tram or car. As we offer prenatal + postnatal classes in all our locations, we also have easily accessible entry spaces for strollers.Our studios have complimentary refreshments in the lounge. There are also S191 sweat + shower towels, grip socks (essential for all reformer classes), hair scrunchies, water-bottles & fem-care products for sale in all of our studios. GET READY FOR YOUR S191 CLASS Come as you are - no fancy designer onesies are needed here. We’re all about having a great time + that often means attending class in whatever makes us feel fab - however functional clothing equates to a better workout; so a pair of leggings, a tee + some grip socks usually does the job. All classes are barefoot/grip socks, please store your shoes in a locke

Know what to wear before every run. Layer reads the weather for the whole time you'll be out, how hard you plan to go, and the gear you own, then recommends one outfit. Choose the kind of run you are planning and how long you will be out. Layer follows the forecast across that window, including temperature, wind, rain, and changing conditions. LEARN FROM ACTUAL RUNS Afterward, tell Layer whether you felt cold, warm, or comfortable. It adjusts gradually as a pattern develops, so one odd day will not rewrite your preferences. USE YOUR OWN GEAR Add jackets, tights, base layers, and the rest of your running kit. Photos are optional. Recommendations use the names of your items instead of generic labels. LAYER PRO Layer Pro adds tools for training and race day: • Race Mode: plan your race, pin fuel reminders and voice notes to points on the course, and invite the people who matter to record a note for a specific mile. On race day, Layer plays each one at the spot you chose. • Fuel practice on your training runs, so race-day fueling is already familiar. • Plan runs ahead, not just today's. FREE WITH LAYER Today's outfit, home screen widgets, your Kit, your run log, Strava connection, and Export My Data are free, with no subscription. KEEP YOUR KIT AND RUNS Sign in with Apple if you want your Layer runs, kit, shoes, preferences, and optional gear photos to sync through your private iCloud account and return after a reinstall. APPLE HEALTH IS OPTIONAL Give Layer read-only access to completed running workouts and it can match them to runs in your Log. Health data stays on your device, and Layer does not write to Health. SUBSCRIPTION DETAILS Layer Pro is an auto-renewing subscription: Monthly (with a 7-day free trial) or Annual (with a 14-day free trial). Prices are shown in your local currency in the app. Payment is charged to your Apple Account when the free trial ends, or at confirmation of purchase if no trial applies. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Any unused portion of a free trial is forfeited when you purchase a subscription. Terms of Use (EULA): https://layertoday.com/terms Privacy Policy: https://layertoday.com/privacy Layer is built for the moment before the run: check the plan, see what to wear, and get outside.
