Intenza Escalate Adjustable Height StairclimberThe Escalate is the only stair climber built to adapt to every body. With 20 adjustable step heights ranging from 4" to 7. 7", it goes beyond traditional fixed step machines to support everything from active aging and low impact rehab to high intensity interval training. Incline training (2040) lets you target glutes, hamstrings, and calves, while decline settings shift the focus to quads giving you genuine control over which muscles you challenge.
