As shown in the video, this is a no excuses exercise that can be done anywhere you can plop that booty on the floor! However, it can be progressed by holding a dumbbell, med ball, baby (yeah, I'm talking to you new momma's!), kettlebell or anything to add resistance!

Perform 10-20 repetitions for 3-5 sets.

Notes on form:
- Feet can be on the floor if you're a beginner or are prone to lower back pain.
- Focus on keeping upper spine straight.
- Squeeze your glutes to tuck your tailbone and round your lower back to support your lower back. Your lower back should not arch!
- For Russian Twists, twist your spine so your chest faces the walls to your right & left. Don't just flop your arms (and the weight you're holding) side to side. It's Russian "Twist" for a reason!
- For leg extension, squeeze your butt even tighter to protect your lower back and squeeze your quads and lock out your knees to support your hip flexors.
- BREATHE! Inhale as you twist, exhale as you extend & retract your legs.

Let me know how many reps you're able to complete in 1 set on IG/TW @cassiebstrong #BStrong!
