I don't class myself as one of life's natural exercisers, but I've been doing a variety of things now for years, and I actually now get a bit angsty if I've not done something in a while. I like variety, so do all sorts of things. I generally do one yoga class a week, one HIIT class a week, and see a PT fortnightly. Around those things...I walk with friends, or a quick 20-30 mins before work/over lunch (also use this time to catch up on podcasts), I'm currently training for a mini triathlon, so I cycle and jog (need to get some swimming in...), sometimes do workouts at home (I've had a Peloton digital subscription, but currently on a short break as am doing more stuff outdoors, have also used Fitness Blender, Apple Fitness, Joe Wicks).
Motivation - it really does set me up for the day, boosts my self esteem (except for running, as I'm rubbish at it, and beat myself up), keeps my mood even, gives me tonnes of energy, keeps my weight stable, good for my bone density and heart health. Ultimately, I've only got one body, and it deserves attention. It's a bit cheesy, but Peloton instructors helped me reframe exercise - instead of viewing it as a chore, another thing to fit in, bottom of the priorities, they suggested turning it around as an opportunity - instead of 'I have to exercise', try thinking 'I get to exercise today'. Seeing how difficult some movement is now for elderly parents/PILs is also a motivator to try to keep as active for as long as possible.
