Manny Pacquiao's Gruelling 20-Minute abs workout ahead of Fight with Floyd Mayweather

Manny Pacquiao's preparations for his $300million (£200m) fight with Floyd Mayweather continue to push him to the limit as he was put through a gruelling 20-minute abs workout.

Pacquiao was joined by fans for the session, before going five hard rounds against two different partners on his first day of sparring ahead of the mega-fight in Las Vegas on May 2.

'When Manny threw out the first punch it felt like opening day of Irish Spring Training,' joked trainer Freddie Roach. 'Manny looked so fresh today. I'm very happy with what he showed me.
