The SP-4605 combines two essential lower-body exercises in one efficient, space-saving machine, allowing users to train both the quadriceps and hamstrings without leaving the seated position. Designed around a carefully optimized axis of rotation, the machine provides a natural and consistent feel during both leg extension and leg curl movements.
Switching between exercises is quick and intuitive, making the SP-4605 particularly efficient for busy commercial fitness environments. The seated position provides stability throughout the movement, while the integrated adjustment system allows users to establish a comfortable and effective training position.
A 128 kg weight stack provides substantial resistance for progressive strength training, with 5 lb incremental adjustments for precise load selection. An integrated rep counter helps users monitor their performance, while convenient storage built into the top cap provides space for personal items such as a phone or water bottle.
With its robust 271 kg construction and dual-function design, the SP-4605 offers an efficient solution for facilities looking to provide comprehensive lower-body training while making effective use of floor space.
