Ok, so let me tell you how this program works? You’ll need to use heavy weights in this XTRAIN arm workout and do between 10 to 16 reps for each exercise. I suggest first trying a weight that is about 70% of your one rep max, and make adjustments as needed. If you can easily do 16 reps for any exercise you should select a higher weight the next time you do this workout. Likewise, if you can’t do at least 8 reps you should consider lowering your weight. In order for this workout to be effective, you need to select a weight and resistance tube that challenges you for every exercise while still maintaining good form. You’ll see us taking notes to record our weights and I encourage you to do the same. This way, the next time you do the workout you can make it even MORE effective!
