Twister Arm Trainer 40–90 lb – Build Chest & Arms at Home

Squeeze, press and twist against real spring resistance, anywhere.

The Twister Arm Trainer puts a heavy-duty spring between two foam handles. Bend it toward you for chest squeezes, press it overhead for shoulders, or twist it for forearm and grip work. No rack, no bench, no plates: it fits in a closet or a gym bag.

Why you'll love it

• 3 resistance settings: 40, 65 or 90 lb – move two pegs between the holes to change the load as you get stronger.
• Heavy-duty steel springs – smooth, consistent tension rep after rep.
• Anti-slip foam handles – a thick, secure grip for hard sets.
• Wrapped U-shaped frame – aluminum frame with covered springs, so it is comfortable and tidy to handle.
• Small and portable – train at home, at the office or on the road.

How to set the resistance

• 40 lb: both pegs in the 1st hole on each side
• 65 lb: one peg in the 1st hole, the other in the 2nd hole
• 90 lb: both pegs in the 2nd hole on each side

The box is marked “40 KG”, which is about 88 lb, the trainer's maximum setting.

How to use it

• Chest squeezes in front of your chest
• Overhead presses for shoulders
• Twists and holds for forearms and grip
• Slow, controlled reps: start at 40 lb and move up when 3 sets of 10 feel easy
