Hi, I am mixed a.m &p.m gym rat... But after we got traffules, It is hard to leave her to go to gym!
At least few things saving me with Truffles is... She is pee pad train in house and potty out side too (finally

So morning, she go potty in my bathroom for pad so if I go gym in the morning. At least I can walk her after I'm back.
My family is in a house when I go gym at night so I won't feel guilty to leave her again after I'm back from work. Cuz kids and hubby walk her in afternoon.
Also you have a lots of nap times of his routine that you can sneak out to gym too.
I used to do weights and cardios same day.. Now... Just one hour of split work out..
And plus put Zumba classes for 2times a week. But I don't feel guilty to her or myself and happy days!
But at least you are lucky to bring your baby to work and etc... You might have to adjestible work out time for first few weeks till he is comfortable in house and your regular routines of times, days week. But just few weeks
If nobady is home and I get ready for work out Truffle goes to bed in playpen Waite for happy mom comes home!
