A senior athlete in Germany lifted numerous sets of 25 repetitions with 375 kg (830 lbs.) on the leg-press, breaking a record for his age group. He did 107 sets in total over three and a half hours.
The sixty-four year-old Kurt Koehler says that the challenge has depended on mental power and strength.
The record has taken place on the last day of the fitness trade fair in the city of Cologne.
The event is an international trade show for body conditioning as well as health. It draws visitors from over 100 nations and features more than 720 exhibitors.
