      Intelligent Assessment

      Knowing your unique pattern of restriction is important in order to release tension and balance your joint motion. It is very common to have one side of the body tighter than the other.


      Skilled Assisted Stretching

      One of the most profound advances in stretching is the evolution of resisted stretching. Studies find that offering resistance while stretching makes a huge difference in the success of the stretch.


      Kinesio-taping SUPPORT

      Kinesio taping is a specialized tape that is soft, flexible, and very stretchy. When we apply kinesio tape to an area, it gently draws the two ends of that area together.

      Frequently Asked Questions

      At iFlex, you will receive a stretching that is based on the latest scientific research. We like to call our style Active Stretching. This is because we ask the receiver to actively contract their muscles at certain points in the stretch- so it is active, not passive. This has been shown to be the most effective type of stretching for increasing range of motion. Specifically, active stretching falls in the family of stretching including PNF (Proprioceptive Neuromuscular Facilitation), CRAC (Contract, Relax, Antagonist Contract), MET (Muscle Energy Technique).

      Assisted stretching is more effective than stretching on your own. With assisted stretching, your body receives the resistance feedback it needs to lengthen muscles and relieve tight joints for increased range of motion, flexibility, pain relief, and more that supports an active lifestyle.

      We recommend that clients wear clothing they would feel comfortable stretching in such as loose, soft clothing, or something they would wear to workout or do yoga in for maximum comfort during your assisted stretching session.

      The needs of every individual are unique but consistency offers the best results. We offer convenient membership packages to accommodate any lifestyle, goals, and budget.

      Assisted stretching can reduce and relieve pain by targeting muscle spasms, sore and tight joints and muscles, and more. Assisted stretching may be able to relieve both chronic and acute pain.

      We welcome people of all ages! Anyone of any age can benefit from assisted stretching.  Anyone under the age of 18 will need to be accompanied by a parent or guardian who will have to sign our waiver.

      All our stretch therapists are heath-care practitioners licensed with the state of Arizona(or nationally), whether they are massage therapists, personal trainers, physical therapy assistants, or yoga teachers. Each Stretch therapist also undergoes a multiple day training and certification process (both online and in person) where they learn the iFlex stretch and evaluation process. You can trust that our Stretch Therapists are knowledgeable and sensitive to your individual needs.

      Derrick Colter

      Hey everyone my name is Derrick Colter I am the new Stretch manager here at iflex stretch studios and I couldn’t be more excited to join the team. I was born and raised in Arizona in the East valley. I attended Apollo college in 2008 and through them I became a certified Physical therapy technician/Chiropractic Assistant. I worked in the chiropractic field for 10 plus years where my main job was rehabilitation therapy showing and doing one on one exercises and assisted stretching for all our patients and helping get them out of pain and improve the quality of their life. Stretching is a great way to not only increase your range of motion and flexibility and also decrease pain in most cases and if you’re an active young athlete or a weekend warrior, stretching can also decrease the chances of having soft tissue injuries as well. I’m looking to do the same for our clients here at Iflex stretch studios. Looking forward to meeting you all.

      As a Personal Trainer, Group Coach, and Nutrition Coach, every day I witness the human body accomplish amazing things, such as walking, running, carrying groceries, lifting heavy weights, and even performing gymnastics. The stopping point isn’t 70, 80, or 90. Remember, you only get one body. Stretching, mobility, and strength training are keys to unlocking that potential. Stretching has been critical to my career. I can’t wait to help you reach your potential to perform better and go beyond pain.
