Jessica - who weighed 240 pounds after Birdie's birth - worked up to 14,000 steps a day and worked out with a trainer three times a week, but has continued to exercise by herself from her LA home during the coronavirus quarantine.

When it comes to her diet Harley encouraged Jessica to eat three, healthy, protein-filled meals and two snacks per day. 

Rather than deprive her entirely of the foods she loves they worked on her having several cheat meals throughout the week. 

Jessica also quit alcohol three years ago and has never looked back.
