exercise has been shown to increase metaboliasm in muscle. By contracting
agonsit / antagonist muscle pairs, appreciable muscle activity can be achieved.
An advanatge of isometric exercise is that no exercise equipment is needed;
people can exercise at home on their own. In the present investigation 16 subjects
were examined during an isometric co contraction exercise video compared to
situps and 8 weight lifting exercises to assess how musch work was done on
each. The results of the experiments showed that the video worked out all 10
muscle groups whereas the other exercises targeted specific muscle gorups. The
video was equivalent to doing continuous situps for 8 minutes, lifting 20 lbs with
a chest press, 10 lbs with a biceps curl, 10 lbs with a triceps curl, 30 lbs
with a lats pull down, 60 lbs of back extension, 30 lbs of abdominal flexion,
40 lbs of leg extension or 50 lbs of a leg curl for 8 minutes.
