It sounds like you and I have a lot in common. I don't consider myself much of someone to enjoy working out or wanting to put a ton of effort in. However, I have found a really good workout regimen that is easy to follow and doesn't take a whole lot of time. Since you haven't worked out in a while, it may be difficult at first, but with consistency, it will get better!
1 mile run/walk followed by
Fuel + Fitness: Horizontal Conditioning video. It's only 10 minutes and feels so good to do after cardio. Plus, you only have to do it 3 times a week
Finish by doing 50 jumping jacks, 10 pushups, and 10 sit-ups three - 3 times
