Hey there. I'm a sprinter and my main events include 50 fly and free. However, at most times, after finishing my race I feel like I could've gone much faster and done much better. I don't feel tired at all. When I try to go faster during the race, it's like something is holding me back. I'm not tired, I'm trying to go fast but it just doesn't happen. I don't go fast even if I pull more efficiently and kick with more power. I've tried doing 100s but I absolutely suck at them. What would you advice? Also, I lot of people have told me that this happens because I don't sprint properly. Any tips on how to sprint properly?
