Recently watching a Golovkin video from sports science, they talk about how Golovkin has great flexibility and can leverage lots of power because of it. I read interviews from Anthony Joshua, Vasyl Lomachenko and Erickson Lubin and they pretty much agree . The problem is that I have like 0 flexibility in a 1-10 scale, i think it's actually really bad flexibility for an 18 year old. So i wanted to know if someone knows about routines or exercises that i can do when i stretch before or after training. Thanks.
Have you ever stretched before? Just do any stretching you can think of. There is no special secret to it. Stretch in the morning, before workouts, after workouts, and before you go to sleep.
To be honest i was really lazy at it and I'm starting to feel the effects, i feel very tense and my a little slow.
Not a bother at all. I'll give you an example of a stretch that can be done both dynamically and statically. Touching toes: Dynamic Version - Touch your toes then stand straight up. Don't hold for any period of time, touch and go. Repeat multiple times. Static Version - Bend down and touch your toes for 10 seconds or however long you like. Most traditional stretching is static stretching. Another good example of dynamic stretching are lunges (without weights).
Flexibility is the easiest thing you can improve as an athlete. Consistency is key. It's not difficult to do some dynamic stretches i.e. arm rotations, leg lifts etc followed by static stretches. What you do will depend on what you're attempting to improve. It seems you're too lazy to bother, though.
