Gym works great for me, I go a few times per week unless I´m sick or really can´t find the time, it´s not a chore, I love to go. I burn 500-600 calories with the cardio part, don´t know about the machines, as they don´t tell me, but it´s enough for a few snacks either way. I enjoy it, the training itself, hey, I can listen to my favourite music and let my mind drift, then they have a nice spacious shower room that´s much bigger than my bath, good coffee machines and a lounge to relax a bit before leaving.
Finally, since I know I’m paying for it anyhow, it motivates me to use their equipment, hot water, blowdryer and coffee as often as I can. They have all kinds of good courses too, I go sometimes but not regularly, I´m not much of a course and fixed times person.
Crisps, they started to sell my favourite brand in a pack of 4 small packages too instead of just a big one, they are more expensive in price/grams, but in practise, if you eat 4 small ones instead of 4 big ones per week, it´s actually cheaper, apart from saved calories.
