I used to be active (going to the gym at least 5 times a week and often doing 1hour + of cardio) every fitness post I’ve said says to lift weights and forget cardio… I don’t know where to begin. I used to have a PT but some of the stuff feels unachievable to me now e.g squats and deadlifts and I am anxious about starting again… how can I start gently but maximise weight loss please? I feel like everything physiologically and physically has declined
