in the process of set up we little home gym . get a treadmill and these be the first set of weight we purchase . they be so much better than the free weight in gym . the material be solid but have a nice rubber like exterior that be very comfortable to hold , do not cause callus skin on the palm or finger -lrb- major problem I have with the gym 's free weight -rrb- , and they be also sweat absorbent to some extent . the last feature be crucial because it avoid the weight from slip during workout . admittedly these be light weight dumbbell so the chance of they slip be much less . I wish these be available in slightly higher weight category as well . I check several store and they say that these be only available in the lower weight , I guess till around 20 lb or so .
