I have been working out for the past 5 months and gains have been moderate (I am an ectomorph, very skinny), have gained around 5 Kg following a workout plan given to me by a trainer. I select weights to which I can do the desired repetitions with full range of motion, usually to failure.
Today, a personal trainer approached me and started selling me the benefits of personal training, we did the same routine I follow but he pushed me very hard with weights almost 70% more than I usually do, he was like supporting me after 6-7 reps of the second set.
My question is which is better, to self train with weight you can do comfortably or start pushing yourself with help of a trainer?
