Just running okay?

NEVER EVER use a treadmill. I hate those things so much, they are in-effecient. They make you waste so much energy and make you feel so slow. Don't get me wrong but my PR for a mile is 4:59 and I ran a mile full speed on the treadmill and I didn't even break 6 minutes. Those 6 minutes on the treadmill were like hell.

Your best option is to probably join (indoor)track if you have one or cross country. But if you rather stay in the gym for inclimate weather then just use a stair stepper and go as fast as you can with the most amount of resistense.

This is pretty much my conditioning schedule for tennis and football and a light ...indoor track schedule (Crazy right?) Its hard but it becomes better for you overall. I don't always have those workouts like 3x a week, only when an important track meet is coming.

Monday : 3.5 mile tempo run, Abs and shoulders+back

Tuesday : 5-8 mile distanse run, Abs, and chest

Wensday : 12x400 keeping consistent times, Abs, triceps and biceps

Thursday : 5-8 mile distanse run, Abs Quads and calfs

Friday : Sprint steep/long hill workout

Saturday : 3-5 mile run

Sunday : Ice my body

Want to know what sucks even more? My track coach is my football coach so he sets me as an example during summer conditioning and he places me with the varsity athletes.

Running is a good start, but the best way to lose weight is a combination of cardio training, weight training, and eating habits.

Cardio: Run/walk whenever possible and remember that if your goal is to lose weight then long runs are better than short sprints.

Weights: Muscle is very efficient at burning fat, so a little light lifting will help. Getting 3 or 5 pound weights to do simple exercises will be useful. That way, you won't be bulking up, but the muscle will be toned and therefore more efficient at burning calories.

Eating: Be sure to drink lots of water. However, you need to make sure that you have a regular intake of foods with sodium in them to keep your body balanced. Go for fresh foods, not prepackaged ones with chemically created sodium compounds. Try to eat a large amount of small meals during the day rather than 2 or 3 big meals. Avoid junk food, red meat, and cheese whenever possible. Stick to vegetables, fruit, white meats, and grains.
