If you’re serious about your training and sprinting faster, you need to focus on it. Squats and deadlifts have their place, but they won’t give you the movement pattern needed to drive your sprint performance. The key is knee behind your glute to build speed and power when and where it counts.
Sprinting isn’t just a “leg” workout; it requires a full-body effort, taxing a well-developed energy system and pushing it to its limits. An increase in VO2 max is a hedge against aging. Your lungs get better at processing oxygen, making you more efficient in everything you choose to do. The more you sprint, the better you get at delivering oxygen to your muscles, resulting in greater output.
