The best way to get prepped for a workout is likely different than you think. If you think stretching your hamstrings is what you should be doing then I promise you’re missing the boat. Take a look at these videos and notice the progression from simple to complex movement; it looks like the first year of a human life! There is no better way to get prepped for swinging a golf club, lifting a weight, running, jumping, etc. than to build up to it--that’s how your body did it originally. These moves are primal, natural, authentic, and absolutely necessary. Mastering the movement patterns in these videos will establish a solid foundation that lowers your risk of injury and improves performance with your resulting workout...and just life in general.
One caveat: Earn the right to do these moves by first removing mobility/flexibility issues. So maybe you do need to stretch your hamstrings…find out by having an evaluation at Movement!
