VIDEO: Venus Williams trains with 79-Year old father, Richard ahead of the 2021 US Open

Although Venus Williams may be approaching the twilight of her career, this hasn't stopped the 41-year old from getting an early start in preparation for this summer's hard-court series, that culminates with the US Open.

The seven-time Grand Slam champion reached the second round of this year's Australian Open, but fell in the first round at Miami, Madrid, Parma and Roland Garros. However, the two-time US Open champ was seen ramping up her preparations for Flushing Meadows, alongside her father, Richard Williams.

The elder Williams was the first coach of both Venus and Serena Williams, and has been a driving force behind their success. Now 79-years of age, Richard Williams was seen assisting Venus with her training, acting as an instructor and motivating her as she completes the exercise.
