Nice way to get a workout! It's a juggling act for Hilary Duff as she carries little Luca in one arm... and a heavy bag on the other

She's become something of gym junkie since giving birth almost a year ago.
And while Hilary Duff was giving the treadmill a rest on Tuesday, the actress still managed to get a mini workout.
Hilary put her strong arms to use, toting her toddler son Luca on one, while holding a yellow bag on the other as they ventured out in Beverly Hills.

Heavy load: Hilary Duff gave her strong arms another workout as she carried son Luca, a heavy bag and extra large coffee while running errands in Beverly Hills

That wasn't all - she also clutched an extra large coffee-to-go from Starbucks which she probably needed to carry all that luggage.
The 25-year-old mother's well-muscled arms got their workout that day.
The former Lizzie McGuire star's legs were toned and shapely as well, proving that those Pilates classes are doing their job.

Glowing: Hilary looked remarkably fit and strong in her workout clothes, and Luca looked cute in his blue trousers, black shirt and trainers

She looked like she'd just put in another session at the gym, for she glowed all over with a sheen of perspiration, including her arms and her face.
Hilary wore a grey tank layered over a yellow leotard, along with clingy blue leggings and blue trainers.
She wore her blonde hair loose and straight, and shielded her eyes from the sun with a pair of tinted sunglasses.
Luca, who turns one on March 20, was cute as can be in blue trousers, black long-sleeved shirt and black trainers.

The golden-haired toddler, who seems to take after his father, Hilary's husband Mike Comrie, was in an easygoing mood, helped to be sure by that blue pacifier.
It seems wherever Hilary goes, Luca goes too and that's just fine with her.
'Mike and I are literally so obsessed with Luca,' Hilary told Access Hollywood. 'He's perfect! We should just be one and done. But I think once your kid starts getting older you miss that baby phase and you go in for round two.'
One downside is that raising a young baby has affected her sex drive.
'It's definitely different,' Hilary said. 'I'm so exhausted at the end of each day, so I'm like, "Can this not happen at night when I'm exhausted?". You find different times to do it.'

Arms free: Mike carried Luca back to the car to give Hilary and her arms a nice rest
