true. i'm not using any smartwatch ke chest strap ke apa. lari togel. masuk event pun sama. just record strava kat phone, pakai earbud pastu train lari sampai habis. dah habis train baru tengok balik. lagi focus, tak stress sangat dan enjoy. kadang kadang boleh kira sendiri bpm dan boleh feel badan sendiri kat zone mana masa train tu. nak share je. hehehe. after all, there is no one-size-fits-all approach, right?
