I get a buzz as in thinking 'thank Christ that is over!'
Haha, me too! I've tried loads of different things and I just don't like it. Hate dancing, aerobic classes, exercise bikes, cycling, cross trainer, circuit training, weight training, swimming (the biggest faff for the most tedium!), sports (all of them), etc. The only really good exercise that I can tolerate sometimes is running because I get a lot of bang for my buck and I can pretend I'm training for the zombie apocalypse. But to be honest I'd rather sit on my arse.
What I have discovered though is that although I dislike "exercise" I'm happy to have hobbies that happen to be physically active. So have helped at stables (I enjoy mucking out and it's hard work), done kayaking (I'm just playing on the water and accidentally exercising), done volunteer work, dog walking, and hiking (I'm just going out for a hill walk with mates/the walking club, I'm not "exercising"). In other words I need to be conned into exercising.
Something I shall be experimenting with is setting myself little targets such as 30 minutes on my cross trainer 3-4 times per week, sit ups, push ups and squats, and each time I do them I give myself a beautiful glittery bright coloured star for my reward chart. Juvenille it may be, but I'm giving it a go because I need all the help with motivation I can get. Would something like that help, OP?
A word of warning though, don't expect to be able to sit all day and make up for it for an hour a day at the gym for example, because sedentarism/sedentary lifestyle is extremely harmful regardless of whether we do the recommended amount of exercise. Generally being more active throughout the day is the way to go.
