This ninja warrior obstacle course takes bodyweight training to new heights by allowing students to traverse a special slackline with vast array of unique obstacles. Everything from an 8' climbing rope to monkey bars provides a fresh, challenging experience, effectively building core and overall strength with fun and engaging activity. Obstacles securely attach via ultra-strong triangular carabiners to 18 loops along the slackline.

Obstacles also swap out in seconds, making for a novel and exciting experience during every attempt. Various obstacles focus on different strengths and weaknesses, providing endless fun and long-lasting fitness benefits.
