Even after years of training, I cannot get myself to like working out. It always feels like I'm dragging my feet, I loathe the long training hours. However, with the recent trend of people getting sick, bedridden 24/7, etc. Before a workout, I'd imagine myself hooked up to a dialysis machine and my procrastination evaporates on the spot haha.
We, myself included, take a lot of things for granted. Sometimes, when I go out for a run, I see people struggling to walk, let alone run. There's an interesting pattern here: when we're young, energetic, and full of life, and topped with "thinking long-term is expensive on the brain", we take the present for granted and end up like the folks in poor condition.
If the first technique doesn't work, try asking yourself "Do I want to train?". 9/10 my answer is "no", so I follow up with "Do I want to end up like them?", there's not a parallel universe where my answer would also be "no", so I train.
Just wanted to share in case it could help someone.
