  1. Another great quick option workout!! Love your videos, plus Jennie and David are so cute.

  2. Hi Amy I really hope I get a reply from you, I discovered your channel about 2 weeks ago and since then I am doing your workouts at least 3 days a week I tried the 4 challenges and the winter Olympics and hiit, my question is I don’t know why every time I do the workouts I feel totally unable to exercise the next day or two days after, I have been exercising regularly for more than two years now, I like your workouts but I wonder the effect I am getting after does it mean I am weak or?
