Anita Herbert in Two-Piece Workout Gear Shares "Summer Shred"

Anita Herbert, the fitness trainer behind the successful Summer Shred program, is pulling a Lego Batman and not skipping a leg day. She posted a video of herself feeling the burn when doing squats and more. "True story 🥲—especially when it's the second leg day this week!👀 Who can relate?" she captioned it. Here are some other ways she stays so in shape.

"When you think of an exercise routine for your core, most people think of sit-ups or planks, which are great exercises for your 'six-pack' ab work," exercise physiologist Griffin Nykor, RKin, CPT, tells the Cleveland Clinic. "Leg lifts are an important complement to that because they get at the muscles that make up the rest of your trunk — your lower back, glutes, hip flexors and your transverse abdominus (the muscle that sits under your six-pack)."

Check out this great video about her favorite high-protein snacks. A sample:

"🩵 Bone broth – 50 calories per bag and 10 g protein Just ask for hot water on the plane or at a coffee shop when you are ready to have it.

🩵 Protein bars – Look for ones that are low in sugar and high in protein.

🩵 Protein powder – I put a serving of iso whey by @onesthealth in my shaker and just add water when I'm ready to drink it. linked in my bio!

🩵 Protein chips – Perfect for snacking on while watching a movie, and the macros are a lot better than regular chips, 130 calories per bag with 17g of protein and only 4g of carbs."

"I usually program a hip thrust variation 2-3 times / week, using different rep ranges," she captioned one video. "You can perform all of these variations with a dumbbell, kettlebell or smith machine instead."

"These tips will level up your ab game 🫡 Train your ABS instead of your ❌hip flexors!" she captioned one great video. "Focus on:

✅ Curling your chest towards your hips

✅ Reducing your range of motion and really focus on using your abs, no momentum.

✅ Squeezing your abs at the top

✅ Lowering yourself down slowly

✅ Breathing correctly: inhale on the way down and exhale on the way up."

"Having strong glutes, quadriceps, hamstrings and calf muscles gives your body a strong foundation and can," sais Piedmont Health:
