13x100m (50m down and back) sprints with 25 second rest. Want to see some examples of how to incorporate sprints with your training sessions in the gym? I've written three detailed workouts based on your particular training goal (either power & speed, muscle building, or fat loss) that each pair a weight training routine with a sprint routine that complements it. The workouts are very demanding and probably not appropriate for someone who is just beginning to train for the first time, but they can be very effective as long as you take care of your nutrition and recovery are on point!
