100% right - I've been training for +20 years and have indirectly coached a bunch of people around me hoping they would get motivated... My son also joined me 7-8 years ago he's now 20 and feels great working out regularly.
If it helps anyone - training regularly not only builds muscles it destresses you and keeps your mind in check. What used to be stressful is now much easier to manage as I'm able to pass these challenges during a training session.
Kudos to anyone starting out - it's never too late to feel better. Cheers.
