Incredible piece of equipment packed with the latest technology. I use my x2 Voltras daily. Primarily for Lat, Tricep and Row and other accessory work. The ability to quickly load the desired resistance as well and eccentric and inverse chains modes keep the training fresh and diverse. The possibilities with the BP Voltra are limitless and you can control directly from the unit via touchscreen or also app based from a device to fine tune even more options. The only challenges are obviously battery charging depending on the load and amount of use each workout and the price point. Build quality is excellent with only the rope itself being something to keep an eye on for replacement depending on angle of rope pull. I’d highly recommend Volta over traditional weight stacks since the possibilities for mounting and use are endless and you can even take a Volta with you for travel or outside the gym with the various accessories for mounting and securing.
