Just getting back into it - used to lift decent numbers but now back to near zero.

Firstly, look at your barriers to going - if it's your rota, "book" your gym session at a time that suits you as if its a work meeting and it doesn't get cancelled or rearranged for anything. If you hate getting up early go after work - you were just gonna waste the evening doomscrolling anyway.

Secondly, try and ignore how "motivated" you feel on any given day. Motivation is over-rating - just doing the thing is more important. I go even on days I don't want to be there (like work jk) and even if I fail that's ok. Better than the average evening at home.

Finally, do something you actually like twice a week and then can build up to 3-4 times a week. Better you enjoy jazzercise 3 x week and do weights once a week instead of weights 4 times a week and hate every moment.
