Stretching needs to be done whether you are twenty years old or fifty years old. It needs to be done. It needs to be done before your workout and after your workout. Ugh, yes I know. I realize it’s kinda boring and you have better things to do, It’s a waste of time right? Wrong! It’s essential, mandatory and absolutely needs to be done!
What happens if you don’t stretch? You get stiff that’s what, Your range of motion is diminished and you are more likely to injure yourself. No joke. You might hurt yourself. Why? Because your joints aren’t loose, They are tight and so when you go to do a movement, any movement you will not be able to move through that movement smoothly and you will twist something, or sprain something.
When you stretch your joints are lubricated(lube gotta love it lol) and that lube called synovial fluid allows you to effortlessly move through joint movements like squats, running, bicep curls, anything!
