Couples who train together, stay together – that’s if San Francisco 49ers star Kyle Juszczyk and wife Kristin are anything to go by.
The fashion designer was put through her paces by her NFL beau Friday when she joined him in a grueling preseason workout.
With the 2025 NFL season looming, the fullback began ramping up his preparation, taking to the field to run a series of drills and Kristin joined him for a ‘dreaded “come train with me”‘ day.
Kristin, whose sports-inspired designs blew up after Taylor Swift wore one her custom puffer jackets to a Kansas City Chiefs game, shared a video to Instagram Friday showing her mimicking her husband’s workouts to Survivor’s ‘Eye of the Tiger.’
The entrepreneur, who married the Niner in 2019, copied Kyle as he tossed a medicine ball over his head and carried out a plank, crunches and sprints among other drills.
On the whole, Kristin managed to hold her own, only occasionally losing her balance and failing to launch the weighted ball as far as her partner.

Social media users were left impressed in the comment section, with one writing: ‘Honestly crushed it.’
‘He’s not taking it easy on you at all lol,’ another claimed, while a third added: ‘Ok but you held your own during that workout- slaaaayed it!’
The couple have endured a turbulent offseason, with Kyle, at one point, appearing likely to return to the Bay Area next season.
Kyle was cut by the Niners in March following eight seasons with the team, only for San Francisco to sign him to a new contract just four days later.
The 49ers had initially decided to cut Kyle, instead of paying him a $4.1m salary this season and up to an additional $500,000 in offseason workout and per-game roster bonuses.
The team took on a $3.6m ᴅᴇᴀᴅ cap charge with the move but brought him back on a new two-year, $8million contract. He was also nearly cut last season but agreed to take a pay cut to stay in San Francisco.
Juszczyk began his career with the Baltimore Ravens after they picked him in the fourth round of the 2013 NFL Draft.
The 33-year-old was one of the first players signed after 49ers coach Kyle Shanahan and general manager John Lynch took over in 2017 and has been a key part of the offense since then thanks to his versatility.

In an era when few teams use fullbacks, Juszczyk has played about half the offensive snaps during his time with San Francisco and has made the Pro Bowl all eight seasons with the team and nine times overall.
He was a first-team All-Pro in 2023 and second-teamer in 2024 after fullbacks were added back as a position for All-Pro the past two years.
Juszczyk had 19 catches for 200 yards and two touchdowns last season, while also rushing for 26 yards and a touchdown.
He has 184 catches for 1,895 yards and 13 touchdowns in eight seasons with the Niners, along with 237 yards rushing and six more touchdowns on the ground.
