Motion Technology Selectorized — twelve machines with the Iso-Lateral motion known from Hammer Strength plate-loaded machines, but with a pin instead of plates. The left and right sides each have their own weight stack. Click a machine to open a larger image and the full specification.
The line is deliberately short and heavy on the upper body: four presses, three pulls, two arm machines, plus legs and abdominals. In a gym it is most often set out as a separate row next to the plate-loaded zone.
On an ordinary selectorized machine both arms lift the same weight stack. On MTS each side has its own tower and its own pin — that is the difference the whole line is built on.
The left and right arm or leg work independently: together, alternately or each with its own load. The stronger side cannot do the work for the weaker one.
The working arms do not move in parallel. Through the movement they converge or diverge, as on Iso-Lateral plate-loaded machines, except that the load is selected with a pin.
Each weight stack carries an additional 2.5 kg plate that sits on the guide rods and is lowered as needed, so it cannot be mislaid.
The frame is made of steel sections with a 3 mm wall and comes in two to four parts, to pass through narrower doors. The weight plates are solid, 25 mm thick, and the belt is Kevlar-reinforced. Seats adjust in 12 mm steps, and the foot supports have a non-slip covering.
Eleven machines have two weight stacks, 75 kg on each side, or 50 kg each on the Biceps Curl and Triceps Extension. The Abdominal is the only one with a single stack, of 68 kg. Maximum user weight is 136 kg on all of them.
Colours: the frame and working arm are chosen from the same palette, the upholstery separately. The images show the machines in black — colours for Hammer Strength →
