According to sources, Tom is willing to do whatever it takes so his bride-to-be "looks the best that she can walking next to him down the aisle."
In addition to joining her strenuous workout sessions, Tom also makes sure that Katie's strict workout schedule goes without interruption by personally booking babysitters for the kids.
Katie has developed quite a fondness for pumping iron, something she was unable to do while pregnant with Suri. Since the birth of her daughter, Katie is said to be hitting the weights at least 4-5 times a week, focusing on building muscle in her shoulders and back.
As TMZ first reported, Katie has recruited the help of the Buff Brides fitness program to help squeeze into her sleek, form fitting strapless wedding gown.
Now Tom just needs to work on his public persona, where can that be recruited from?
