**For ages 13 and above.** Systema is a Russian Martial Art founded by the late Colonel Mikhail Ryabko and Vladimir Vasiliev. Systema was designed to develop individuals in a combative style which upholds the intrinsic value of all human life. This is why it is non-destructive – even of one’s enemies. Through the use of simple exercises, breathing techniques and massage work, Systema helps you to build a strong mind and body. Here is what you can expect: **Warm ups** Class begins with warming up each of the systems of the body – from the breathing, muscular and nervous system, each component needs to be properly engaged. **Thematic studies** Fetching from a huge pool of drills and sometimes even crafting specialized ones, our instructors format a logical progression of the concept being shared. Depending on the ability of the class, the drills are modified to be at the optimal level for learning, with suitable modifications given to students based on their individual performance. **Application of concepts** After the thematic studies, some time is given for the students to apply the training – the intensity is decided upon by the students under the supervision of the instructor. At times, the instructor will request for the students to push themselves, while at other times they are there to taper in the sparring to a productive level. **Cool downs** The cooldowns are usually done in a way both the help the class recover from the higher intensity application section as well as to revisit the concepts again in a calmer manner. This helps to ensure everyone is reminded of the key points. Sometimes we do a little massage. **Training circles** At the end of every training session, we circle up to share a few words about the training. This tradition was handed to us from our founders and is an integral part of our training. ### **Address** Lor 23 Geylang, #03-05 37, Singapore 388371 ### **Schedule** Saturdays 10AM - 12PM ### **Booking Information** * Please contact **98225900** to find out how to book this class. * The instructor will reach out to you once you've booked the class.
