Actor Alec Baldwin.

Alec Baldwin loves working out with his wife Hilaria.

The '30 Rock' actor has lost weight and toned up thanks to vegan yoga instructor Hilaria's advice and credits her for his physical transformation.

A source told Us Weekly magazine: “They love to work out as a couple. On a recent charity bike ride in New York they were hugging and laughing, they're really happy.

“Her healthy diet has helped him get on the right track.”

Alec, 54, recently admitted he is always “happy” when he is with his 28-year-old spouse.

He said: “I'm happier when I'm with her. I'm not as happy when I'm not with her. Let's face the facts: I got lucky.”

Hilaria - who met Alec a year ago - says she's happier than ever and loves being married to the actor.

She said: “Being married is pretty incredible. To look at a person and say, 'I'm going to spend the rest of my life with you' feels wonderful.”

And the actor is pleased Ireland, his 16-year-old daughter with ex-wife Kim Basinger, gets on well with his spouse.

He said: “My daughter is as in love with her as everyone else.” - BANG Showbiz
