“I’m very connected to my body, so if I’m going to experience stress, I’m probably going to experience it physically,” she says. “So it’s usually a good idea for me to go do something physical to get rid of it. I kind of have to think of myself as a horse or something—time for a run around the paddock,” she told Women’s Health.

2. She Does Strength Training

Beckinsale will do squats while also doing something else simultaneously, like a bicep curl. “Before stepping into the squat rack or grabbing those heavy dumbbells, be sure to check in with your squat form. Stand in front of a mirror and begin with your feet slightly wider than shoulder-distance apart, giving yourself a good base of support. Throughout the squat, make sure your heels stay on the ground and your knees stay behind the front of your toes. As you begin to lower into the squat position, think about pushing your hips to the back of the room (or whatever is behind you). Continue to lower your glutes until parallel with the floor,” advises ACE Fitness.

3. She Does Cardio

Kate will do cardio, including the rowing machine. “To do the seated row with a weight machine, start by sitting on the weight bench with your knees bent and by grasping the cable attachment. Your arms should be extended and your shoulders stretched slightly forward. Slowly pull the cable to your waist, until your elbows are bent and your shoulders are back. Then slowly return to the starting position. You'll feel tension in your back and arms,” says the Mayo Clinic.

4. She Stretches

Kate stretches after every workout and is impressively flexible. Try this Calf Stretch from the Mayo Clinic: “Your calf muscle runs along the back of your lower leg. To stretch your calf muscles:

• Stand at arm's length from a wall or a piece of sturdy exercise equipment.
• Place your right foot behind your left foot.
• Slowly bend your left leg forward, keeping your right knee straight and your right heel on the floor.
• Hold your back straight and your hips forward. Don't rotate your feet inward or outward.
• Hold for about 30 seconds.
• Switch legs and repeat.
• To deepen the stretch, slightly bend your right knee as you bend your left leg forward.”

5. She Eats Protein

Kate eats protein before a workout, like chicken or eggs and also eats salmon for lunch. “Protein is an important macronutrient that your body needs for increasing calorie burn, decreasing hunger, and maintaining muscle mass. Not only that, but a diet with a sufficient amount of protein can actually help you to feel full. The RDI for protein is between 46 and 56 grams of protein for an average adult. A 3 oz. salmon fillet will actually give you around 21 grams of protein, which is almost half of the amount of protein you need for the day,” says our sister site Eat This, Not That!

6. She Trampolines

Like fellow star Eva Longoria, Kate has used a trampoline to get fit. Doing so can work your core and drain your lymphatic system. “I just got into trampolining, and it’s the greatest thing. There’s this woman, Lauren Kleban, who does LEKFit, and I think she’s a genius because she streams classes online. It makes you feel kind of jolly!” she has said.

No pain, no gain! Kate Beckinsale, 48, continually wows fans with her ageless body. Whether rocking a bikini or red carpet attire, the actress looks incredibly toned, taut and slender. Today she shared some behind the scenes footage of a new ad she’s shooting, clad in a swimsuit. “BTS fun in Turks -also reminder that girls and some boys like amazing skincare for Xmas @mrvlskin,” she captioned it. How does she stay so fit?

1. She Does Yoga

“You’ll find yourself in Bulgaria, and you don’t know anyone, and they’ll say, ‘Well, we have a trainer who’s available, and he’s literally called The Punisher,’” Kate told Women's Health. The magazine says she “packs yoga workouts recorded by Jessica James and Mandy Ingber.” “I haven’t been injured while doing an action movie, and I think it’s partially from practicing yoga," she said.

2. She Does This Exercise

Kate recently revealed some of the workout moves responsible for her famously fit figure and also showed off her majorly impressive flexibility. She started out by executing a series of hanging leg raises, followed by knee raises on a pull-up bar. Next up, battle ropes! However, instead of getting just a hardcore arm workout in, the actress added a side lunge to the mix. To complete the workout, Kate’s helped her do some stretches, revealing just how flexible she is. “Do you have any bones? Omg,” singer Peter Frampton commented. “Damn, the only way I could get either of my legs that far back would be to amputate it and hold it back there with my hand,” joked one of her fans.

3. She Puts the Work In

One of Kate’s trainer’s Brad Siskind of Gunnar Peterson’s gym, revealed that Kate’s workouts are always this intense. "The whole hour is work," he told Women’s Health. She generally begins with a full-body workout composed of eight compound exercises, each working two muscle groups simultaneously—as can be evidenced in her latest workout video. Other moves include biceps curl as she squats, or situps with combination punches. Following the intense set she will complete 90 to 120 seconds of a cardio interval, like rowing or the VersaClimber, then repeat the entire circuit with heavier weights, added bands, or faster reps. Finally, following the 45 minute circuit workout, she’ll finish with a cardio interval using a rubber Inertia Wave, or one-leg pushes on a curved SkillMill treadmill. And, last but not least, she will do stretches.

4. Sometimes She Does “Two-a-Days”

"I wake up, eat something, and go straight to the gym," she told Women’s Health. "If I’m going to do cardio, I’ll do it later on in the day," she said.

5. Sometimes She Trampolines

Kate has been known to trampoline. “It makes you feel kind of jolly!” she said. Fellow star Eva Longoria is also a fan. "Take the time to find your own rhythm," she captioned one post.
