I have a deep hateret against classical gym. Just not my thing. Mostly due to all that 'evil-eyes', all pointing into direction of a 'puffy-fatso'
To keep the flexibility and condition up, I mostly bike (which is individual sport) and swim in a local pool, that carries significant 'epithet' of a 'tropical paradise' =). You can imagine what that is. I have a year card and go whenever I want, if they're open.
Most of the time I go and swim for myself in a big pool (also individual). But they also offer aquajogging, aquarobic, aquazumba and aquabiking. Most of the ladies are smaller than me, but I am not the biggest either. They have that very cute trainer
, I call him AquaNazi as an open joke (in front of him) and he laughs a lot when I do it.
However - it comes up to the person itself. Although the trainer gives me quite hard time during the aquajogging sessions, he respects if I cannot follow through the whole exercise. And he is never rude about it. Even more: he has made relaxing routine for me to repeat when I cannot keep up.
That's why I always felt comfortable in that setting and kept going. Made all the difference to me. And swimming is also good because it doesn't hurt your ankles and doesn't lead to any unwanted weightloss that easy either.
