Biceps Showdown!
Ambra and Sabrina display their biceps to each other in an initial staredown that leads to the first test where they compare the strength of their arms and shoulders to prepare for the clash.
The challenge involves various tests of both strength and endurance using dumbbells weighing between 2.5 and 7.5 kg in each arm.

Weights and Push-ups
The tasks range from simply holding the weights with elbows at 90 degrees, to bicep curls, to arm lifts overhead.
Of course, push-ups cannot be missing, as well as a curious form of arm wrestling from a plank position where the goal is to make the opponent lose balance.

Arm Wrestling
The grand finale is a series of arm wrestling matches, each awarding a point, until one of Ambra or Sabrina reaches 12 points overall, thus winning the match.
The loser is forced to admit that her opponent is stronger before leaving the stage to her.
