Understanding Activity

This app was designed for participants in Understanding Society: The UK Household Longitudinal Study. As part of this study, participants aged 16 and over will be sent a Garmin smartwatch and asked to install and wear it, to collect data on their physical activity, sleep, and geolocation. The geolocation data will be collected directly from the respondent’s smartphone, if the phone and Garmin are within Bluetooth range. If they are not in range (suggesting that the participant has gone somewhere without their smartphone), the geolocation data will be captured by the Garmin. The purpose of this app is to retrieve all data from the Garmin as well as the geolocation data from the phone. The Garmin data will automatically be transferred to this app at regular intervals. In addition, participants will be asked to complete a brief daily survey within the app. This survey consists of 11 questions and takes less than 3 minutes to complete. The data collected by the app will not include any information about who the participant is. Understanding Society researchers will download the data collected by this app, process the data to derive indicators that do not identify you or your locations, and make the anonymous data available to researchers. The Understanding Society study is conducted by the Institute for Social and Economic Research at the University of Essex and funded by the Economic and Social Research Council.

Whether you’re pre or postnatal, over 50, recovering from injury or just ready to feel better, we meet you exactly where you are — and guide you forward, with structure and support. Rooted in contemporary Pilates and layered with biomechanics, applied neurology, movement science, injuries and special populations. Our method is calm, clinical, and completely personal.
This isn’t about keeping up — it’s about reconnecting with your body and building strength that lasts. Our method starts by understanding how your body moves today — so we can guide you toward how it’s meant to move tomorrow. Each class is built around progression, not performance. We teach clearly, adjust in real time, and support you every step. el Estudio was created for people who want more than just a workout. For those who want to move with clarity. With strength. With trust in their own body again.
 We guide every client with structure and care — whether you’re starting from scratch or refining years of experience.
Here, movement is education. It’s alignment and control. It’s breathing deeper, standing taller, and walking out feeling like yourself again.
 This is Pilates as it should be: intelligent, human, and built around real life.
