It is very rare for some persons to get injured in their first step of jogging, and it can only happen if they step on something and they twist their legs and hurt their ankle. It is true that I haven't been jogging for a long time, but since I have been active in doing push-ups, I don't have any problem with jogging. If I decide to jog today, I can jog even though I don't stretch my body, and nothing bad will happen to me because this push-up exercise has helped my body to be fully fit to do any physical exercise.
Being in pushups exercise for sometime makes a person fit for other activities including jogging also. But that does not totally remove the potentials of facing some pains and strains during or after jogging. I have being in pushups exercise for quite sometimes now at least over 6 months and I have also been in period jogging exercises. This does not totally save me from the last experience I had during the night sleep after going for Saturday morning jogging which I had series of muscle pulls little above the knees behind. If I haven't been engaging in jogging before I could have been thinking that it was because I was new to it.
The human body has a way of reacting to stress and it can happen anytime. A person can also twist his foot on his first step during jogging. I engage in jogging with at least 100 others every Saturday and Sunday since it's a street combined club workout. I have seen some folks sustain sprain in their first steps and withdrew from the exercise completely.
Also individual strength differs too. What you are capable of doing painlessly may take me a lot of pains to achieve or series of pains to get adapted to. We can always take care of our body by taking enough rest, eating good foods, taking enough water and ensuring that we don't exercise beyond our capabilities.
