From the reviews

My full and honest review is too long to write here. Anyone geographically close enough to join and train with Sifu Olavarria should run there before his new location fills up! I started training with him and his highly skilled instructors back in 2006, as a police officer. It truly changed and saved my career!

★★★★★ — Edwin, Dec 2022

My journey in Wingchun began one year ago with Sifu Cesar. He is a highly skilled and inspiring instructor. It is no secret he is passionate and knowledgeable about the essential principles and underlying philosophy of Wingchun.

★★★★★ — Sonia, Jan 2023

⭐⭐⭐⭐⭐ I am thrilled to share my experience at the Institute of Defensive Méthode, where I’ve had the privilege of training under Grand Master Sifu Ceasar Olavarria.

★★★★★ — David, Jan 2025

If you want to learn true and authentic martial arts, this is definitely the place. I’ve always wanted to learn martial arts to learn how to fight and when I started learning under Sifu Olavarria I learned so much more.

Your first kickboxing class at Institute of Defensive Methods

Nervous about walking into a kickboxing gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

Kickboxing is a contact sport. Warm up, pace yourself, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
