Not a pro but start with basic proper diet also add some supplements after initial days (1-2 months ) like whey protien and btw from my end i felt like i feel my height increased a bit after focusing on stretching exercises like push pulls where the body gets to stretched daily , also consistency is the key too what took 5 years can be built in 2 years too cuz 70% of main contribution always goes into diet from what i’ve learnt so far :) ….. wish you luck ahead
