Kyle can improve his speed and endurance by using a FITT program. This program focuses on four key elements: - Frequency: How often he trains (3-4 days a week)- Intensity: How hard he trains (gradually increase speed and effort)- Time: How long he trains (gradually increase workout duration)- Type: What exercises he does (sprints, interval training, strength training, flexibility) By focusing on these elements, Kyle can create a training plan that will help him run faster and longer during football games.
