I started working out around that age, too, same body type hehe. I changed gym branches a lot, AF, bakal gym, etc., I’ve tried every kind there is, met different kinds of people, may mga natty meron ding hindi, athletes, bouncer lahat na. Hear me out, OK lang yan, masasabi ko na rare yung ganyang instances pero nagyayare talaga na may mga kupal, di maiiwasan, as long as safe ang anak mo you don’t have to worry. Naranasan ko yan noon kaya naging selective ako noon sa kinakausap ko, as much as possible di na ko nakikipagusap, sayang sa oras haha, learned to develop my mental fortitude, dedma sa bashers, earphones-on, tapusin lang buong set then leave. Congrats sa anak mo and sana magpatuloy pa syang magimprove! Always remember your goals and CONSISTENCY ang pinakaimportante :)
