Pull. Push. Bend. Twist. The Xertube is strong enough to
support any exercise.
Add resistance to build balance and strength in ways you never
thought possible with the SPRI Xertube. With braided rope-like
construction, it’s the most durable tube available today — holds
up to extreme stress during your most intense training session.
Anchor the Xertube to any secure object, step on it or even use
it in partner drills. Once you’ve conquered light resistance,
move on to more challenging models — each is color-coded, and
available here. Measures 7.875" x 2.5" x 8".
