This cardio exercise requires you to have some core muscles, else it will be very difficult to make right and it won’t last for long, thus, not very effective.
However, if you have practiced normal push-ups for a long time and feel you’re ready for a more demanding exercise at home – try the Spiderman Push-ups!

Spiderman push-ups / press-ups are very HARD for me to do. I guess I should keep dong the regular push-ups for a little longer.
Ye, spiderman push ups can be pretty tough..
