When one of the lights flashes green, Miller explodes forward like he's hitting the hole, while the VertiMax pulls him back and forces him to activate every muscle fiber in his massive legs. When the lights flash red, Miller freezes in place to avoid a false start that would cost his team five yards during a game.
After the grueling workout, it's recovery time. Miller dealt with ankle issues toward the end of last season, and wants to ensure he stays healthy through the playoffs this year, so Alexander places electrodes on Miller's legs to stimulate blood flow. Then, Miller slides on NormaTec Recovery sleeves - leg wraps that use steady mechanical pulsing to help Miller's body flush damaged tissue away from his ankles, calves and thighs and reduce inflammation and swelling. This is a technology Miller uses during the season as well, and he credits it with helping him get his legs back after a punishing 25-carry game against a locked-in defense.
