1) If you are always tired and a little overweight (or more), get checked for sleep apnea issues at a sleep study center. If you have it, it is sapping your energy.

2) If you are like me and don't like exercise much (nor the time investment) but can no longer deny its benefits, do what I'm doing and do HIIT spin cycle 3 times a week for 25 minutes. It totally works. Feel free to google it, there's a lot of interesting research at this point.

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.
