If you fully extend and fully descend on every rep.. it's pretty easy to tell you are training in the same range of motion my friend!
Yes and thats why i advertise full range of motion, i see alot of people not doing it. So i wonder how they can keep track of there progress?
Always for example when i do dumbbell chest presses i always lower the dumbbells so deep they touch my anterior deltoid/upper chest muscle just to push up them again so i have straight arms and then push them together so they make a small sound.
But i see alot of people in my gym who does only lower the dumbbells until they think there upper arm and lower arm together makes 90 degree angle. But it's hard to always know that every rep they do that they exactly go to 90 degree and not 1-2 degrees lower or higher. Which means it will be hard for them to actually keep track of there progress.
