Mine's really simple
First start with stretching.
Then 1 round of brisk walk,
then 1 round of slow jogging
that's warming up the lower body ~
Then 1 set of maximum pull-ups/chin-ups
+ 2 counts of special jump pull-ups (basically you jump up till your chin's over the bar, then u hold on at that height and slowly release your arm's strength to reach back to the ground ~
Special jump pull-ups help a lot to train your pull-ups/chin-ups as the efficiency rate of training your arm muscles is 2X when coming down from the bar.
I trained from a maximum of 4 pull-ups/chin-ups to now 12 (recently hit it)
After that 1 set, I sometimes do some tuck jumps. And by that time my body's almost fully warmed up so I will start my real jogging then.
Usually I will jog only around 4 rounds (estimated 2km?) but with consistent high speed. After that it's back to another set of maximum pull-ups/chin-ups followed by more special jump pull-ups ~
When your body's all warmed up, doing static exercises such as pull-ups/chin-ups or sit-ups will be even more effective.
And that's when I do my usual sit up, crunches and leg raise.
There is something to note about crunches though. There is a BIG difference when u do it right vs when u do it wrong.
When doing crunches, always breathe in and when u do so, ONLY use your stomach muscles to slowly move your upper body up a little. There is no need for your elbow to touch your knees. On top of that, try to always look up so that you won't use your neck to help u do the crunches.
If you don't do so, it is possible to strain your neck and the crunches will not have hit the right abdominal muscles.
If you did it right, after like a set of 25, you will definitely feel muscle pain/stretch in your lower stomach abdominal muscles
After everything, I also stretch to cool down my muscles to prevent ache the next day
