Todd revealed to Grayson on the Chrisley Confessions podcast on May 6: "It is such a joy to be able to be in the gym with you to work out. To see you looking the way that you look, you look so good."
Grayson replied: "Folks, that is all muscle. I was 134 in November-December. I'm 165 right now, so 31 pounds." Todd admitted: "Well it shows…[You looked] way too skinny."
To get to his muscle goal, Grayson incorporated a plethora of workouts including running and strength training, as well as weightlifting, jumping and resistance exercises.
Grayson isn't the only one flaunting his dramatic transformation in the family – Todd also gained major muscle and sister Savannah Chrisley is on a journey to shed some weight.
Todd recalled that, while serving time in prison from January 2023 to May 2025 for bank and tax fraud, he consistently worked out daily by lifting weights.
The reality TV star was supposed to serve 12 years, however, President Donald Trump fully pardoned both him and wife Julie Chrisley, who was also sentenced to seven years, but served two instead.
Savannah showed off her dad's new "jacked" transformation on social media, joking: "I'm not going to lie, it's hard," while feeling his bicep.
Savannah, 28, has been candid about her weight loss journey and admitted that she's used GLP-1 weight loss medication in the past, in an effort to shed the pounds.
She revealed on her Unlocked podcast: "Right now I am almost 160 lbs. Probably more than that. I like my weight to be 135, around there."
Savannah admitted that one of her previous medications gave her awful side effects, and made the foodie lose her appetite, so she recently switched over to a new version of GLP-1s after undergoing blood tests.
The TV star shared: "I love food. That's the hard part. So when I'm on the shot and I can't eat, I'm like, 'I really love food.'"
She added: "I love tirzepatid. It doesn't give me all the side effects that some of these other ones give people. So then I can compare my bloodwork before taking it, and after taking it, and see where my biological age is, how my A1C is, all those things."
