Extra strength resistance bands (45lbs-65lbs) are a must if you plan on using your Squat Harness on the go! With 2 or more of these bands, you can also mimic just about any cable machine exercise.  Resistance bands represent one of the greatest modern fitness innovations and they broaden the spectrum of indoor and outdoor core exercises. They are safer on your joints than free-weight or cable machines, and the ascending tension makes them ideal for exercises like chest fly’s or straight-arm lat pull down’s.  I recommend making bands a part of your regular routine; whether in place of other forms of resistance, in addition to other forms of resistance, or as just a warm-up aid.
