Elevate Your Lower Body Workout with BFR

Let’s take yet another dive into Blood Flow Restriction (BFR) training, featuring three killer lower body exercises: Bulgarian split squats, walking lunges, and body weight squats! 🏋️‍♀️🏋️‍♂️

🩸 What is BFR – It’s all about temporarily limiting blood flow to your muscles with specialized cuffs while you work out.

This can help with muscle growth, strength, and endurance using lighter weight, or relative to your starting point without any external load! 🔗

▶️ Attach the BFR Cuffs on the top part of your thighs, inflate to the intended pressure, and calibrate. If needed, grab some dumbbells for extra resistance.

Here’s the BFR leg day routine from @marta.bichowska

1️⃣ Bulgarian Split Squats:

🔹 Step one foot back onto an elevated object
🔹 Drop down into a single-leg squat.
🔹 Feel the burn, but know it’s working wonders!

2️⃣ Walking Lunges:

🔹 Keep those cuffs right where they are.
🔹 Take a step forward with one leg.
🔹 Lower your back knee close to the ground.
🔹 Walk it out, feeling the pump with each step!

3️⃣ Body Weight Squats:

🔹 Feet shoulder-width apart.
🔹 Drop your booty low, keeping your chest up.
🔹 Feel the BFR as you power through the struggle!

🔥 These exercises with BFR will leave your legs shaking and your muscles screaming for more! But remember, safety first – consult with a fitness professional if you’re new to BFR. ⚠️

The Science Behind the Fit Cuffs Pressure Calculator V2

Does auto adjusted blood flow restriction (BFR) training improve muscle growth and strength compared to fixed-pressure cuffs? In this first 8-week within-subject study using the Fit Cuffs BFR system, researchers found no meaningful differences in hypertrophy, strength gains, or perceived discomfort between autor and non-auto conditions. When pressure was prescribed relative to limb occlusion pressure (LOP) and training variables were standardized, both approaches produced significant improvements. Here’s what coaches, clinicians, and lifters need to know about auto vs fixed-pressure BFR.

Figures 2 and 3 display grouped scatter plots comparing autoregulated (AUTO, gray circles) and non-autoregulated (NONAUTO, red triangles) blood flow restriction training before (Pre) and after (Post) an 8-week intervention. Figure 2 shows significant increases in rectus femoris and vastus lateralis muscle thickness at 30%, 50%, and 70% femur length in both conditions, with no differences between groups. Figure 3 shows significant increases in rectus femoris cross-sectional area (50% and 70%) and 1RM strength for single-leg squat and knee extension in both conditions, again with no between-group differences. Asterisks (***) indicate statistically significant pre-to-post improvements.
