A:Answer Hi There,
The BowFlex BXT8J Treadmill has a minimum ceiling height requirement of your height plus 15.6 inches (approximately 39.7 cm).
o determine if your ceiling height is sufficient, add 15.6 inches to your height. For example:
If you're 6 feet tall (72 inches), you'll need a ceiling height of at least 87.6 inches, or approximately 7 feet 4 inches.
This measurement accounts for the treadmill's deck height and ensures safe clearance during use.
