“Her number one concern is just to be healthy for her baby,” her trainer, Jeanette Jenkins, told PEOPLE at a party celebrating the 100th birthday of American icon Jack LaLanne in Los Angeles on Thursday. “She’s going to be the most incredible mom.”
Jenkins says the mother-to-be has been maintaining a regular workout schedule.
“We work out Monday through Friday, but we just keep it at a moderate level,” says Jenkins. “We stay within her doctor’s guidelines and work out anywhere from 30 minutes to an hour so it’s not anything exorbitant.”
