Thanks for the hints. I already do regular exercises and keep my weight more or less - it's just getting harder every year. With 30 I never had to think much about this while with 40 it has become an annoying regular routine I have to go through.

If you're not already, look into doing a couple of resistance training sessions per week. You don't have to be He-man lifting huge weights, in fact you're better not to be. Focus on core and "all of body" movements.

You'll not only feel stronger and look healthier, you'll also burn a lot of energy. And as you get older, maintaing strength and flexibility guards against aches, pains and injury.

I'm currently using variations of the 7-minute workout (7-min.com) + some minor weight lifting.

Any amount helps, but cardio benefits only start to kick in at 20 minutes or above, as I understand it, from the research.
