Authenic product from Groupon at a great price and free shipping. You can't beat it. Works wonders especially if you can't afford a home gym. I chose to add the Trx suspension straps to my workout regimen. I would recommend them to anyone serious about getting an intense workout at home.
TRX provides a great workout in virtually any location. Very little space is needed. I especially enjoy that the exercises may be tailored to individual fitness levels. You can make things as easy or as difficult as you need.
I love, love, love this equipment! It is high-quality, durable, and exactly what I was hoping for when I ordered it as a Christmas gift for my husband. The door mounts are small, but effective, and we love TRX!
