There isn't much that can stop Stephen Curry in his tracks. The two-time MVP and NBA champion is on top of the world right now after his team cruised to their second championship in three years a few months ago.Currently in Beijing, China on his Asia tour, the point guard will be keeping one eye on free agency proceedings and will no doubt be excited about Golden State's chances of winning back-to-back titles in the 2017-18 season. The Dubs are sure to face tough challenges along the way. The Western Conference is stronger than ever before and Kyrie Irving's trade demand could lead to the formation of another super team. But while in China, the 2015 and 2016 MVP faced a unique challenge that proved too much. Steph posted a video on his Twitter page of himself doing push ups on a glass floor, looking down from an incredible height. The video can be seen below. Anyone with a fear of heights please exercise caution.

The perennial All-Star was able to do three push ups before his arms seized up and he rolled away from the glass flour. His wife, Ayesha, admitted on her Instagram that it took her five minutes to pluck up the courage to walk across the glass.

CHALLENGES

With the offseason in full flow, fans around the world are looking forward in anticipation to what should be a thrilling campaign of NBA basketball. 

The free agency period was one of the best in recent history, there are new teams ready to challenge throughout the league and there is a real buzz of excitement.

But the pinnacle is still the Golden State Warriors. Draymond Green recently told GiveMeSport that he doesn't feel any team can challenge the Dubs if they reach their full potential, and with Curry and Kevin Durant in their primes, it's hard to disagree. 

The Warriors are a juggernaut and Curry is the main man. Having signed a new NBA-record contract in the summer, he will be keen to get back into action and add another ring to his already incredible list of honours. 

The Oklahoma City Thunder, the San Antonio Spurs and of course the Cleveland Cavaliers are seen as the biggest threats to the Bay Area franchise, but having added two deadly sharpshooters to their roster and re-signed Andre Iguodala, Shaun Livingston, Durant and David West, it's hard to look past the California-based team.
