The perfect at home step workout, all you need is a step or your own staircase.
Start with a 5 minute warm up – any cardio or dynamic movement will be good.  Something like:

• light jogging (out or on spot)
• stair climbing or stepping
• marching on the spot
• arm swings, knee lifts, arm circles, butt kicks combo

then folow through the workout and repeat the whole thing twice

Be sure to stretch and cool down after.
