Even those transverse abdominal muscles that rarely get targeted and are the biggest problem for the "mom bod". This will have you in pain for days. I'm a very fit female and this works all of my abdominal muscles plus my shoulders and back and chest.
The product is made very well and will last a long time. The Ab Carver Pro is no joke. You will get a great workout with this piece of equiptment. It doesn't take long see and feel the results. It's easy to use and stores easily on a closet shelf.
If I could design the suit I would make the legs about an inch longer, but if you want the feel of a Aikiki without the look of swimming in your tighty-whities, this is a great suit. I've recently picked up swimming for exercise and quickly noticed my board shorts were not designed for serious swimming. It is also a much smaller suit to carry around when compared to board shorts. So far I have been very impressed with the Aikiki Men's Race Endurance+ suit. They are comfortable to swim in and rise out easily. I've heard from some posts that these run small, but I ordered by usual 32 waist and it fits perfectly. It is obvious tighter than my board shorts, but that is how they are supposed to fit. Think of them as another layer of slightly less revealing skin :-).
No problem with the zippers, zipped a few times to see if there's any catches and all was smooth. I'm really impressed! - especially for the price. The soft fuzzy layer inside was a plus - soft and warm. I ordered the small and it fits a little big but it'll be perfect when I layer up underneath. I was too scared to order the extra small and it be too small for when I layered up. However, one thing this jacket didn't have was a ventilation zipper option - I'll just have to layer lighter for the sunny days on the slopes. . This will be my favorite ski jacket - there's a small zipper on the front where I can slip the lift pass in, allowing an easy scan through the jacket. so glad I got the small. I am 5' 3", usually wear a small in workout clothes, I think people who wear medium can also fit into this Small ski jacket. I can hide my hands inside the sleeves - little long but I prefer it.
If you are worried about quality - don't be, I was delightfully surprised!. I use it to get my computer to work, and also when I travel with my kids. I love this backpack. It is really great quality and nice and big.
