Alright. One day upper body (chest, arms, stomach, back)
Then one day lower body (lower and upper legs, squats (lower back and thighs) etc.
You can swtich between upper and lower body and just fill in various stomach and back exercises throughout. Just remember to give it a break a day after training. Don't "over-train" a particular muscle group. And best advice; Get a training partner. Someone you can count on for motivation and vice versa. It really helps.
Atleast 15 minutes of running each time as warmup. Just find your tempo. Don't stress it. You just wanna get that pulse up. Running 7-10 km/h (ie 4.5-6 miles/hour) should get you ready without wearing you down. And that breath control during running is great.
