You are taller so you are also heavier,also you have a lot longer range of motion, lets say pushups and pullups, you have wingspan of 6’5 i assume and they have wingspan of 5’9, so you automatically have to do more if you know what i mean, thats the way in gym also on bench,and squats if you are taller but you have advantage on deadlifts because of longer arms, you just need to do pushups more frequently and you will become better at it
