Gymnastics requires strength, flexibility, endurance and balance and is thus needs a great deal of physical training time in addition to the actual skills which are performed. 6 apparatus for the guys. Gymnastics actually means "the naked art" but we don't do it that way... and, indeed, the original Greek variety involved naked boys performing field sports like javelin and discus, and wrestling - so very different from what goes on in 21st-century gymnasiums! And that's a strange word too, because in German it means 'High Schools'! Whatever. Let's admire the work put in by modern gymnasts. Even when they are just chilling in their gyms, the excellent body image built by the sport is very obvious.    

The perfect sport for strength, flexibility, skill and endurance. Much to admire here.  

We all need a balanced lifestyle. Plenty training - yes, but other relaxations are important. For today's guys, however, their lifestyle IS balance, and training for the strength and agility which that requires. Mainly, but not exclusively, hand balancing.
