Here is a super quick fat burning workout that requires no kit (by that I don't mean perform it naked, though, go for it, as long as you are at home ), I mean it requires no equipment.
So here goes:
30 mountain climbers
20 push ups (off a wall, staircase or sofa if necessary)
10 Star Jumps
Rest 75 seconds exactly
Repeat. 3 times.
Make sure to warm up thoroughly first
