Nowadays you come across it everywhere, personal trainers are no longer a trainer, no they are life changers! They can solve everything you have had trouble with in recent years (sport, nutrition, motivation issues, stress, etc.). I take it that before you call yourself a personal trainer, you have had a solid education? This is by no means the case for everyone, nowadays a course is apparently sufficient for most. Or even that is no longer enough, just enough experience with 'pumps' is sufficient. https://gelukkiglijf.nl/motivatie-en-inspiratie/personal-trainers-die-zich-coach-noemen/
