We've seen many people do extraordinary feats here at Guinness World Records, but some of the most impressive achievements come from within the fitness realm.
As this week is Men’s Health Week, we’re showcasing some noteworthy athletes who are the epitome of endurance and strength.
Whether it's dads running marathons or repeat record holders who have stopped at nothing to break a record, here are a few male title holders who are pushing themselves to their fullest potential.
Most consecutive muscle ups (male)
Muscle ups are Maksim Trukhonovets’s favorite exercise.
The Belarus-native spends most of his time training in the gym to complete records such as these, and actually also holds the record for most consecutive ring muscle ups.
Considering himself a master in the field of strongman attempts, Maksim completed this record with a total of 26 without pausing.
Most consecutive bench presses underwater
Fitness enthusiast Greg Wittstock from St. Charles, Illinois, USA broke this record title to combine his love of water and weight lifting.
This challenge was particularly difficult as the guidelines state that no breathing apparatus of any kind may be used for the attempt and a minimum barbell of 50 kg must be used.
He managed to accomplish a final total of 62 by the end of his time underwater.
Highest standing jump (male)
Sometimes it’s hard to believe the limits the human body can be pushed to!
Brett Williams from Fort Worth, Texas, USA worked vigorously hard to achieve this title, and practiced for three years before breaking the record.
After landing a height of 1.651 m (5 ft 5 in), Brett’s main motivator was to show others that they are capable of building their fitness goals, even when it seems impossible.
Fastest time to jump across 10 swiss balls
The fastest time to jump across 10 swiss balls is 7.8 seconds and was achieved by Neil Whyte (Australia) on the set of CCTV - Guinness World Records Special in Beijing, China on 12 January 2016.
Neil had three attempts in total but failed his first two. On his last attempt, he managed to just beat his previous record of 8.31 seconds!
Fastest 100 m running on all fours
Sprinting 100 m is already a taxing speed challenge, but imagine running that distance on all fours!
Kenichi Ito took back this title after it was taken from him in 2013, to prove he was the ultimate four-legged champion.
He regained his record running on all fours with a time of 15.71 seconds at Komazawa Olympic Park Athletic Field, in Setagaya, Tokyo, Japan, on 6 November 2015.
