Answer
well CJ, whenever you gain muscle, you gain weight. A.K.A... workout! as your muscles get stronger, more toned, and if your doing certain exercises, you'll get faster, you gain weight. just last summer i gained 30 pounds of muscle. The best way by far to get stronger is to use weights. go to a gym, or your own schools weight room. to increase speed, you can do many things:

1. run stairs. sprint up stairs 1 stair at a time, 2 at a time, or 3. 1 stair= acceleration. 2= running power. 3= deep power.

2. foot work drills and ladder drills.

3. plyometrics

4. 40-80m sprint. the shorter the sprint(40m, no less) focuses on acceleration and technique. these are very good. 60-80m, to keep gaining speed after you reach your acceleration peak.

5. suicides: for cariovascular and muscular endurance.
