FITS ANY SIZE SMARTPHONE
Best ABS workout
Best ABS workout! I do plank twice a day (morning and evening) and after 3 min. my body was shaking. The apps makes this exercise a game so you don't focus on time. My first round was 1 min. 47 second and my ABS were burning next day. Highly recommend!
I was very skeptical at the beginning but I decided to order it OMG is my 3rd day and my ABS are on fireee!!, I'm a fitness instructor and I thought it will be piece of cake and boring but not at all is a GREAT WORKOUT SUPER FUN AND EFFECTIVE. I'm actually recommending this product to my classmates . I Love itttttttttttt!!!!
Great way of doing exercises!
I bought this for my son for 2 weeks. He uses this Stealth Core Trainer everyday. I tried it too and found it really fun. It truly works. Wishing if we can have more games to play, it will be perfect. We love Amazon fast delivery service. I strongly recommend this Stealth Core Trainer.
