I like the Inspire Fitness FT2 Functional Trainer for serious weight lifters as it comes with dual independent 160-pound weight stacks. They function separately, so you can use both stacks or work on one side of your body. Furthermore, the weight stacks are upgradeable from 160 to 210 pounds each.
Even a force multiplier feature allows you to double the amount of resistance. In other words, the maximum weight that the Inspire Fitness FT2 Functional Trainer will enable you to lift is 800 pounds (including the upgrade and force multiplier).
The Inspire Fitness FT2 Functional Trainer also features a Smith bar that connects with a weight stack. Most Smith bars use free weights, which can be quite a pain, but not with the Inspire Fitness FT2 Functional Trainer. The Smith bar connects to the weight stack to make doing presses easy. The Smith bar also features a top lockout feature, so you can keep it out of the way when not in use.
Moreover, it also comes with various safety catches if you drop it. When it comes to doing presses, the Inspire Fitness FT2 Functional Trainer is one of the safest machines. The FT2 requires an optional, highly adjustable bench for your incline and bench presses.
