Having just turned 40 I realise it's kinda now or never to get the fittest I can with body health longevity in mind. I currently do BJJ 3 x per week, weights 3 x per week and running 2-4 x week. My goal WAS to run an ultra this year but I realise that is a singular focus that takes a lot of time and effort. I want to gain a bit of size and also love BJJ so just running is no longer my goal. I also started losing significant weight, not necessarily because of running but I believe mainly cos I just don't feel hungry when running, unlike after weights or BJJ when I feel like eating heaps. My new goal is to put on about 8kg (currently only 62kg), continue with BJJ as much as possible and maintain some decent level of running. I am doing basic lifts at the gym and eating around 3000 cals per day. I really have ZERO idea what I'm doing with regards to putting together an effective training schedule while also eating enough to gain size. Am I trying to do too much? Any advice would be massively appreciated to get me in some kind of routine. I'm not a natural athlete either, just a dude who wants to realise the best version of myself.
