After having tried a few Powertec machines already, I am confident that anyone who’s dedicated to becoming more fit can get a lot of value out of them. If you are a exercise junkie, you are going to love using Powertec’s fitness gadgets:

Powertec Fitness L-CT Leverage Maxi Crunch: one of the best crunch machines on the market. If you want to do crunches like the pros without putting too much pressure on your back, you are going to need this cool gadget (make sure you catch it before it goes out of stock!).

Powertec Fitness L-TB T-Bar Row: one heck of a machine for performing back rows, shrugs, and dead lifts. Now that’s how you build a super strong back.

Powertec L-SC Leverage Squat / Calf: you can’t have a solid body without proper lower body workout . This squat machine helps you exercise areas you are not strong in to build an all around killer body. It’s one solid machine!

Powertec P-PR Power Rack: a cool weight training system for squats, rows, dead lifts, and more. Now this is for those of you who want to go a bit hardcore and do killer lift training. A very solid machine, well-built, and not that expensive either.

Powertec P-LM Lat Machine: a very well built and quiet lat machine that lets you work on your back area, triceps, and more. Another cool machine to build and improve your muscles in areas that you may not be strong in. Very easy to assemble and get started with.
