Video Camera in Hd

My mom's friend bought this video camera in Costco for $200.00.The video camera was very small and when you record it your voice sounds different but on the good side the pictures were not blur and the pictures were in Hd.Hd stands for Hi Definition.I use it to prove my mom's friend that I stretch and do strength training.When I mean about strength training I mean that I do 20push ups,20sit ups,20squats,20leg lifts,20squat jumps,and an exercise I do not know yet.I do this every round.I do strength training 3 rounds every time.
