Professor Lucas Lepri shows how to finish an armbar from the closed guard, when the opponent defends by applying pressure. Lucas demonstrates how to isolate the arm and control using the collar grip and the cupping the elbow. As he climbs his legs up to secure the armbar, the opponent starts to apply heavy pressure, preventing Lucas from finishing. Lucas now switches the grips on the arm and reaches for the leg. This leg control allow him to spin under the opponent while still controlling the arm. From here, Lucas is able to force the opponent down and is able to finish the armbar submission.
