Distance Running And Sprint Endurance
Depends on volume: If you are well trained (running 2 years plus), and truly sprint specialized (distances 400 m and below) then running distances (say 5 miles or greater) will probably slow you down. This is because 1) distance running can to some degree train fast twitch fibers to act more like slow twitch fibers, and 2) distance running will take from training volume that could otherwise be used for speedwork. ...Read more
Yes: Running is an excellent exercise for building cardiovascular endurance; if you run distances you will improve your slow-twitch muscle tone and over time as you decrease body fat your muscles may appear more defined; if you focus on sprinting you will engage fast-twitch muscle and may see more of a "mass" effect; if you are trying for body-builder muscles strength training in gym is your best bet. ...Read more

Yes: Incline walking and sprints will both increase the intensity of the workouts you do. This will boost metabolism of your muscles, making them hungry for energy. Try to incorporate some type of speed workout or incline workout roughly 1-2 times a week. Overdoing it can lead to injuries. ...Read more
Specific: Lighter weights with many reps will help build endurance for that specific movement. Curls will not help you run longer. Being stronger in the upper body will allow you to maintain better form longer and keep you going longer (if your legs permit) by not fatiguing the upper body as quickly. Dynamic weight training will build strength over a greater range of movements. Good Luck ...Read moreSee 1 more doctor answer
