Is 25 minutes a day on an exercise bike enough?

Q: I'm now at 81kg, and am 168cm tall. I'm aiming to get my weight back down to 65-70kg. I've purchased an exercise bike, and would like to know if 25 minutes per day on the bike going to make any difference.

Mozzy: Of course you will notice weight loss!  As for how long it will take...everyone is different.  Don't worry about that.  Try increasing your exercise bike to 35 minutes after about 6 weeks or so.  Adding in strength training will do you wonders and will get you where you want to be quicker.

Make sure that whatever exercise you ultimately choose, that you are enjoying what you're doing.  This will make it something that you will be motivated to do for a lifetime.  That's why variety is the key to lifetime leanness.  If you're just going to stop your routine after you reach your goal, then it's the wrong exercise.  Good luck.
