Reese Witherspoon has not let her devotion to fitness dwindle since entering lockdown with husband Jim Toth, 50, amid the coronavirus pandemic.

And on Saturday afternoon, the 44-year-old actress put that devotion on full display when she was spotted cruising through the streets of Malibu with her son Deacon, 16.

Witherspoon kept her mouth and nose covered by a mustard toned scarf as she rode atop a pastel green bike.

The Academy Award winner suited up for cycling in a black muscle tee paired with coordinating athletic shorts and a fanny pack.  

Reese protected her eyes and face from the sun by sporting a pair of mirror shades and a black baseball cap.

Her signature blonde tresses were neatly tied into a ponytail that poked out from under her hat. 

A plethora of gold chains hung down from the Walk The Line star’s neck, while her Apple Watch rested on her left wrist.
