The hollow hold (or hollow body hold) is a foundational isometric core exercise that trains full-body tension, stability, and posture. Popularized in gymnastics, it teaches you to engage your deep core muscles and flatten your lower back against the floor
How to Perform the Hollow Hold

🔥 Get into position: Lie flat on your back, press your belly button toward the spine, and actively flatten your lower back into the floor so there is no gap underneath
🔥 Lift upper body: Bring your chin to your chest and lift your shoulders and shoulder blades (scapula) slightly off the ground
🔥 Extend arms and legs: Raise your legs straight out and lift them a few inches off the floor while pointing your toes
🔥 Hold: Keep your quads and glutes tight and hold this tension for 20 to 60 seconds
Modifications & Progressions
If your lower back arches or comes off the floor, you need to regress the movement to protect your spine
💥 Beginner: Keep your knees bent at a 90-degree angle (tabletop) or hug them to your chest while keeping your shoulders off the floor

The Bulgarian split squat is an advanced unilateral leg exercise that involves placing one foot elevated behind you on a bench or box while squatting with the opposite working leg. It builds immense lower-body strength, corrects muscle imbalances, and can isolate either the quadriceps or glutes
Perfect Form Setup & Ex*****on
🌟 Find your stance
🌟 Elevate your rear foot
🌟 Keep it stable
🌟 Squat down
🌟 Drive up
You can progress this movement by holding dumbbells at your side (suitcase), holding a single dumbbell at your chest (goblet), or even using a barbell

Basic form tips:
💥 Put your full foot on the box
💥 Push through the heel of the working leg
💥 Avoid pushing excessively off the back leg
💥 Keep your knee tracking over your toes
💥 Stand tall at the top
1️⃣ Improves Balance & Stability. Since you’re standing on one leg during part of the movement, each leg works independently which helps correct strength imbalances between sides
2️⃣ Functional everyday movement. The movement pattern closely mimics climbing stairs or getting onto elevated surfaces
You can progress the exercise by:
💥 Holding dumbbells
💥 Increasing box height
💥 Slowing the lowering phase
💥 Adding a knee drive at the top

Keeping the movement slow and controlled is more important than depth. A good progression is:
💥 Assisted pistol squat holding a pole/TRX
💥 Floor pistol squat
💥 BOSU-assisted pistol squat
People with knee, ankle, or balance issues should usually master:
💪 Regular squats
💪 Split squats
💪 BOSU bilateral squats
⚠️ Important cautions ⚠️
This is considered an advanced exercise. The instability significantly increases difficulty and injury risk if technique is poor
