My Muscles Are Shaking Just Watching Gabrielle Union Crush Her Full-Body Workout Routine

Quick question: is secondhand fatigue a thing? Because that's what I'm feeling after watching Gabrielle Union crush her full-body workout routine. The 46-year-old actress just offered fans a peek at some of her favorite exercises to do before judging NBC's America's Got Talent on Tuesday nights, and good grief, they look intense. Gabrielle shared a series of videos on Instagram Stories to highlight the seven moves she relies on for firing up every muscle group, from kettlebell swings to quad holds. Ahead, take a step-by-step look at her routine, and be sure to check out her determined game face!

01

Kettlebell Swings

Gabrielle opted to kick things off with some good ol' kettlebell swings to work her glutes, core, and arms.

With her legs spread apart and both hands on the kettlebell, she swung the weight between her legs . . .

. . . then swung it back out in front of her until it reached eye level and she was in a standing position. Easy as that!

Cable Crossovers

Next up, she worked her chest muscles with a set of cable crossovers.

While concentrating on her breathing, she pulled the crisscrossed cables downward toward her hips . . .

With the TRX band anchored above, Gabrielle fired up her arms, back, and core with some rows.

Gripping the handles with her palms facing inward, she leaned all the way back . . .

Lying Stability Ball Leg Curls

Lying Stability Ball Leg Curls

Time to target those glutes and hamstrings with swiss ball leg curls, which Gabrielle apparently isn't a fan of, as evidenced by her caption.

She started with her feet planted on the ball, booty lifted off the ground, and hands firmly planted on the mat below . . .

. . . then rolled the ball toward her using her feet.

05
Weighted Hip Thrusts

Weighted Hip Thrusts

Weighted hip thrusts were her fifth move, accomplished with a little help from a circular sandbag.

Gabrielle worked her glutes by starting with her arms spread across a workout bench and the sandbag situated in her lap. She lowered her booty until it almost hit the floor . . .

. . . then thrust it back up to the starting position.

06
Lying Overhead Reach

Lying Overhead Reach

Using the same sandbag, the actress ignited her back, shoulders, and arms with some lying overhead reaches.

With her back firmly planted on the bench, Gabrielle lifted the sandbag backward over her head . . .

. . . then lifted it back up above her.

07
Quad Holds

Quad Holds

Last but most certainly not least, she got down on all fours for a set of quad holds, which she accurately described as "hard asf."

With her hands gripped around dumbbells and knees lifted off the ground, she first lifted her left foot off the ground for a few seconds . . .

. . . before doing the same with her right foot. Phew, that looks difficult!
