AUCKLAND, NEW ZEALAND - David Tua (52-4-2, 43KOs) hits the pads with his new trainer Dave Hedgecock following a press conference in his gym at Onehunga Mall in Auckland. Tua, standing at 5'10, is training for his upcoming fight with 6'8 Russian giant Alexander Ustinov (28-1, 21KOs) on August 31 at Claudelands Arena in Hamilton, New Zealand. Ustinov returns from a stay-busy win in April, while the 40-year-old Tua has been inactive  since the August 2011 decision loss to Monte Barrett. Tua has struggled with weight in the past and his recent photos indicate the heavyweight veteran is not in the best of shape. Tua's main sparring partner is the very tall Julius Long.
