WHY SHOULD YOU BE TRAINING WITH A TRX
I love the TRX because it can train strength, balance, flexibility and stability. But it also can help the user scale the exercise to fit their needs. Making it a top piece of equipment even for a home gym.
The TRX website clearly states why you want to use a TRX, “… to develop strength, balance, flexibility and core stability.” Let’s discuss flexibility and range of motion, stability and strength.
FLEXIBILITY AND RANGE OF MOTION
When we talk about flexibility we are talking about muscle lengthening to improve range of motion. The TRX can be used to help us move into a greater range of motion than we would be able to on our own. Why? Because you can use the TRX as a support system, de-load the exercise and ultimately increase range of motion.
And range of motion is directly correlated to power, which is the result of strength training. But how can range of motion be correlated to power? Let me explain.
Stored elastic energy is what allows us to be explosive and powerful, whether that be for running, jumping or swinging a club. This elastic energy is stored in your muscles and you can think of your muscles as rubber bands. We want them (your muscles) to lengthen like a rubber band and then “snap back” explosively. The more you pull/stretch the rubber band the more speed it snaps back with. So the more range of motion you can access in exercise, with proper stability, allows you to have the potential for greater stored elastic energy and therefore more power.
For the lower body that support comes in the form of holding on to the foam handles with your hands. Take a side lunge, for example. If you hold the handles in your hands you will be able to use your upper body to help you control the decent (lowering) and pull yourself back up. This support or de-loading will allow you to “sit into” a deeper range of motion. If done correctly, it can also help you use the proper muscles throughout the entire movement pattern.
If you put your foot into the loop and perform a side lunge the exercise will feel entirely different. That is because you are no longer supporting yourself to achieve a greater range of motion. You are now challenging your balance, stability and strength. I consider the foot in side lunge to be an advanced variation, and I would not recommend starting here for beginners.
It is worth saying that there should never be pain when working to improve your flexibility. If you have a previous or current injury pushing yourself into a new range of motion may make things worse. You should consult a professional before trying.
STABILITY
How a TRX is designed demands you have stability in order to perform the exercises. The more challenging the exercise the more stability is required as you use the straps while moving. Including variations like single leg, single arm and adding resistance like a dumbbell will all increase the stability demand of the movement.
The TRX can also be supportive. For someone who is unsteady or recovering from an injury the TRX can be used to give them more support to remain stable through their range of motion. A great example is the squat. If you struggle to sit down to a chair without “plopping” or using your hands, the TRX can help you gain the stability to control the movement.
Improved core stability is another advantage of training with a TRX. You can use the TRX to challenge your core stability in exercises you are already doing, like a plank or mountain climbers. Or you can more advanced exercises like a fall out or complexes that include multiple movement patterns to really tap into your core stability and muscular endurance.
As a side note, in order to have good core stability you need ALL of your core muscles to be operating effectively AND synergistically. And your core stability is important because it helps transfer force from the lower to upper body (and back), and to keep your spine healthy (and keep good posture) and prevent injuries.
STRENGTH
And of course the TRX can help increase your overall strength. Now, used by itself you aren’t going to build large muscles or an immense amount of strength because you are using your bodyweight as the resistance.
You can add additional resistance if needed. Holding on to one handle will doing just about any movement and holding a dumbbell in the other hand is an easy way to add resistance. Think of doing a side lunge, in the large range of motion you get from holding on to the handle, but adding more resistance by holding a weight in the other hand. Another example, this time for the upper body, would be a single arm row with a weight held at the chest. This will really challenge your core strength (anti-rotation) and your back muscles.
