New exercise regimen that I hope to start soon

I hope to exercise for at least an hour 2 to three times a week.  I know I am unable to exercise on Fridays as I have a morning appointment.  I feel like going somewhere and just dance, move, walk, etc.  I wish things would come easily for me.  I pace and walk slowly, but that is not the exercise that I feel will help me to lose weight.  It clears my mind and it isolates me from the world, but it won't tighten my abs or glutes.  It won't help me slim my arms or thighs, nor has it always been good for my legs.  I want to be able to do what is hard.  I am thankful that I have the opportunity to do so.
