I’m in my early 30s, but recently realised that I’ve been struggling with physical energy/muscle strength all my life. I hated PE at school and uni, have always been the worst at doing exercises. My MIL is in her 60s and is so much more physically capable than me: she would take all bags, a pushchair with my youngest in it and would be running in the front, with me trying to catch up out of my breath few meters behind. Whatever I do around the house I need to have regular sofa breaks, etc. I’m very bright but struggling to get far in my career because I feel like I’m always tired and not ready for a challenge. My mum is the same as me. Is it just the case that some people are born with more physical reserve than others or is it to do with some health issued (I have PCOS, but slim and my insulin/sugar levels have always been great + I developed hypothyroidism recently, but I’ve struggled with energy levels for many years prior to this)? Anything I can do to lift my energy up? It now really has an impact on my life (struggling to keep up with a full time job, 2 primary aged kids at home and the whole household), feeling tired all the time. Thanks
