Find a good CrossFit gym. Nothing compares as a metabolic workout. CrossFit is constantly varied functional movements performed at high intensity.

You workout alongside others, which is an incredible hack to keep you going. Typically there is a focus on weight lifting and then some kind of Workout of the Day (WOD). As a result, you will get stronger than any runner and you will have greater endurance than any weightlifter. Like all fitness, consistency is key. I found the more I worked out, the more I wanted to eat healthier. I also got better sleep.

Crossfit has a reputation as unsafe, but I find that as long as you know your limits and learn the fundamentals, you'll be find. All gyms worth their salt have coaches that should enforce good technique. Half the battle is just getting to a gym.
