Your doing 40-50 working setes to failure during your training. That's over training. Try cutiing your sets back to one with failure and 2 drop sets. Machines are a lot easier to use then free weights. If your worried about injuries then your going too heavy. At the end of the day, you will decide what your going to do. I will say that most who use machines already have a good physique and are on the older side. You being in your early 20's and limiting yourself to just machines isn't fair to what you could accomplish if you would get out of your comfort zone. Your doing a lot of over training which would result in a better chance of injury then going to actual failure with free weights for one set. Check your ego and watch the growth...
