It is no secret that Jennylyn Mercado has one of the sexiest bodies in the industry.
But have you seen her working in action?
If you're following her on Instagram, Jennylyn documents her workout sessions.
Aside from running, the Kapuso actress also actively practices cycling.
Sometimes, she goes a level higher and does "brick training," a full bike workout, followed immediately by a full run workout.
For her birthday week, she did Pilates, a series of movements that will stabilize and strengthen one's core.
See her intense upper body strength?
The moves may look simple, but they take a lot of precision and control.
Jennylyn, indeed, takes fitness seriously.
