I've posted this in another thread.
Parcells and Testaverde were big on QBs doing heavy squats to keep in shape and improve the zip on their passes. Romo learn this from them when they were here but probably wasn't able to past few off seasons due to his back surgeries.
Here is the article.
Testaverde's workout regimen key to his longevity

CHARLOTTE, N.C. -- The
Vinny Testaverde jokes never seem to stop. He once handed off to Bronko Nagurski. He was in the same draft class as Y.A. Tittle.
Funny thing though, the jokes end when the 44-year-old quarterback walks into the
Carolina Panthers weight room -- and starts doing squats with the linemen.
"I don't think there is any quarterback that I've been around that works as hard as Vinny -- and definitely not as strong," said Jerry Simmons, the Panthers strength and conditioning coach.
It's probably no surprise that two of Testaverde's closest friends in the NFL are Simmons and Arizona strength and conditioning coach John Lott. He met Simmons when they were together with the
Cleveland Browns in the early 1990s, and Lott when they were with the
New York Jets in the late '90s.
Testaverde has combined their two philosophies into a weight-training and conditioning program that is the key to Testaverde being the oldest NFL starting quarterback to win a game.
While many men his age were sitting on the couch Sunday working on their beer guts, Testaverde was throwing two touchdown passes to move past Joe Montana into eighth place on the career list with 275.
Testaverde's tireless workout regimen includes cardiovascular exercises and lifting, specifically squats for strength in his legs.
"People see quarterbacks and they think, 'Oh, he has a strong arm.' But really the strength in your arm doesn't just come from your arm," Testaverde said. "It comes from your hips and your legs. I think the squatting has helped me tremendously to stay healthy and to have that longevity."
