What can I do on a functional trainer that I can't do with dumbbells?

Cable work keeps tension through the whole range, so movements like chest flyes, face pulls and rotations feel different from dumbbells. The adjustable pulleys let you set the angle for each exercise.

Is it good for beginners?

Yes. The guided cable path is easier to learn than free-weight barbell lifts, and the adjustable pulleys let you start light and progress. Pair it with a bench for pressing and rowing.

How does it compare with a single-stack home gym?

A functional trainer gives you two columns and far more exercise angles. A single-stack machine usually offers heavier resistance but fewer movement options.

Can I train legs on it?

Cable squats, pull-throughs and glute kickbacks are all possible, but resistance is limited. Serious leg training still needs free weights or a rack.

Does it need much space?

It needs a clear area around both columns so the cables can travel and you can step in and out. Measure your room against the frame footprint before buying.
