be this a total workout ? heck no ! that say , i think everyone should have one ! and why ? because it be great for the day you do not work out . it be silly , it be fun , and it give you a bit of a pump . for the price , how wrong can you go ? i lift hard 3 day a week . on my off day , i do cardio and shake weight . i give this thing heck for about 15 minute . and i really believe it be deliver some extra cut to my muscle . could i get the same thing with dumbbell that i already use ? sure , i suppose ... but this be different and give I a break from dumbbell . i gotta say , i be very surprise at how much i like this thing . anyone who buy this as they primary workout be go to be disappoint . so just do not be that lazy , and you 'll find this as a great supplementary workout piece . i would not be without mine !
