- Hi, we've added another great accessory to AeroPilates Precision Series line. The double looped hand and foot strap is a great way to add comfort to your AeroPilates Reformer workout. The smaller inner loop is for your arm work, easy to hand hold and the outer loop, the larger loop is for your footwork. Again, it's very padded, it's easy to change out on your Reformer and it even comes with its own carrying case.
