I used to NEVER stretch, mostly because I didn't feel it necessary to do so 👎 This resulted in loss of flexibility and an achy body all the time. I ended up staying away from the gym.
But stretching is incredibly important for all of us, not just for lifters. However, for us lifters, we ask, "WHEN🕐 is the best time to stretch?" There's so much debate on this topic but I found the answer on @Muscle_and_fitness:"To summarize…don’t stretch a cold muscle before training, and don’t stretch the muscle you are in the middle of training. However, DO stretch the antagonistic muscle to the one you are training during your workout, and once the session for the body part is complete, finish it off with two or three intense 30-60 second deep stretches." In other words, stretching should be done AFTER training. You should be aiming for those nice, deep stretches - this will be painful, yet doable (do not overdo it). And, please, do not skip your stretches. If anything, you'll find that you will improve in the gym 💪
