All the ladies who want to lose weight from tummy,hips and arms...

1-how does your budget look like? Can afford another work out machine?

2-Can you find an extrememly stable object, about 8 inches high, on which you can stand? That will be replcacement of your stairs. You can get those 2X1-1/2 feet about 5 inches high plastic platforms from work out shops get 2 of them.
Buy two of those platforms. DONT DO THE WORK OUT SEE IS DOING!!! atleast at start.

3-how about working out twice a day.

Once we get that stair things we can get your lower body in shape, with out a problem.
