Equivalent to lifting 20 pounds. Perfect for regular workouts and
intermediate muscle strengthening.
Very Robust (30Lbs)

Our suggestion
Buy the elastic tube that seems most suitable to you plus one from a fair range
above. This way you can use the second one when the first one has made you stronger...
