In Greg Whiteley's six-part documentary series, which built up an enthusiastic fanbase after hitting the streamer in January, the young 💲 athletes of Navarro College's 14-time national championship-winning cheerleading team repeatedly lift, throw and catch flying teammates, many of them already 💲 nursing injuries and at risk of exacerbating them.

Often, these stunts don't go as planned - bases holding flyers high in 💲 the air shake before the whole formation of bodies collapses to the ground.

Concussions abound, as do ankle injuries and swollen, 💲 twisted limbs.

Barker arrives at practice with a back injury 💲 after ignoring coach Monica Aldama's advice against competing with another team, Aldama still makes him participate in practice.
