What kind of weightlifting workout should i do to gain speed?

Should i be doing more endurance? With high reps lower weight?


Or heavier weight less reps?|||If by speed you mean short distance, like a 100m sprint, low reps high weight. If for a long distance run higher reps. Look at olympic athletes. Sprinters have huge legs from low rep workouts. Marathon runners are small from high rep workouts.|||Well in general, cardio exercises is the #1 way to go to increase stamina and speed


Also in addition to that, do lower weights with higher amounts of reps to tone and increase muscle endurance
