Welcome Hans!
Congratulations on your past bodybuilding success. I know what you mean about being tired and feeling other things too like being moody, hungry, thirsty, feeling weak, etc. even when looking ripped and strong with a bodybuilding physique.
Cool that you've embraced powerlifting and strongman training and competitions. We have a variety of others who complete in those same areas. I like the idea of feeling and being strong, but I've never been able to get really strong while staying injury free, so I don't know what it feels like to lift super heavy weights, just kinda heavy weights

Thanks for joining our community.
All the best and welcome aboard!
