In the video, I'm demonstrating cable reverse flyes with a TRX attachment. Few people think about using a suspension trainer as a cable attachment. It puts a completely different spin on exercises like reverse flyes, Y-raises, face-pulls and even some great bicep and tricep exercises.
You can even put exercises together for some really smooth complexes and circuits. It's been a game-changer for me.
If you want to build huge muscles, you must continually challenge them by placing a greater demand upon them. If you stick with the same stress level month after month, you'll quickly reach a point where your body is used to the stress and won't need to adapt (i.e. grow) anymore.
