Question: under arm batwings, do these  work with success?
Document: The arm slimmers work pretty well but the construction makes them every difficult to put on without help. Not back if you have a work out buddy.
I use the abdomen slimmer and thought I would try the arm slimmers work great and sweat up a storm, which is the point
I had to get TWO of these because the first one never showed up.However, it does work;definitely makes the arms sweat more than just doing arm workouts without them.
My arms are my problem area, and I figured if the belly band is great, I'll give the arm bands a try. They are comfortable and I feel the difference in my arms after a work out
Idk if they are gonna break like others' have, i just recently got them, but so far they are holding up, and big enough to wrap around my arm several times, which makes them work even better!
The bands work well they are just a little small. They completely fit, I just wanted them to be a little tighter. However as I keep using them and the size of my arm shrinks then they will be perfect!!! I would definitely recommend!! !
This product seems to work great. It definitely makes a difference in the amount I sweat in my arm area. Only time will tell if there is an actual noticable difference, but so far I am very pleased and would recommend this product to a friend!
These arm bands do work as well as the bands I had from another brand(Golds gym). They don't create much of a sweat and they're too long in length. I used my old golds bands that were a bit worn out until I ordered and received my new pair of the better brand.
I would like to say how happy I am with my recent purchase of these arm slimmers. I did not know if they would work and only purchased them based on some reviews I read. When I work out I can see the sweat draining down my arms and I can honestly say that my arms are slimming nicely. I am so happy with my purchase.
I've noticed a real difference in the size of my arms using this product. To really enhance the sweating process, moisturize your arms and then wrap in Saran Wrap. Put on the arm slimmers and let it do the rest! They're actually big enough to wear on your thighs. It's the sweating process that causes you to lose inches.I'm retired so I'm able to wear them during the day. If this doesn't work for you, wear them while you are working out!
Answer: yes
