This is actually a set I use
- base 2 - Push-ups
- base 1 - Pull-ups
- base 2-4 - Sit-ups (full) + Bycicle crunches (for the sides)
- base 2-4 - Jumpies - Start in a squat position, on your toes. Jump. Land on your toes and slowly lower yourself into a squat again, while on your toes. Repeat. (calves and thighs . hands folded on the small of your back for balancing)
- Run on the fronts of your feet or do sprints
base # is for making different repetition sets, and having it established helps when you need to increase the reps.
Then do the set x3, x4, or x5 depending on strength vs endurance gain and time constraints. (larger reps with a smaller number of sets for str, opposite for end)
So you might do 3 sets of
20 push ups
10 pull ups
30 crunches x both types
40 jumpies
Alternate the work-out days with the running-conditioning days. And, if you are working out consistently through the week, try to take a day off for recovery.
Pull-ups are not entirely necessary but if you end up cutting them then add the base to your push-ups
I always found working out to be easier without having to use equipment.
It also helps prevent unbalancing your strength, as well as increasing all around muscle coordination.
