Very good advice above , I think the most common issue is glute inactivation but all the other factors mentioned are important too . I ' d add that the warm up is very important too , your glutes need to be firing during your warmup and throughout any sprinting you do . Gluten isolation work as part of the warm up works wonders for preventing hamstring strains . It re programs the body to utilise the muscle while sprinting which can be an issue even if you are strong in that area . Also I do thing direct hamstring work in the gym does help but certainly can ' t compensate for other factors . Eccentric loading of the hamstring is important to keeping the muscle more resistant to strains . <| sep |> Religion by its nature is made up . Anyway , I ' ve never classed myself as Christian , and I don ' t class it as a Christian festival , it ' s evolved past that . For me it ' s a festival of family , friends and happiness
