To celebrate, I thought you might like a sample of the brand new IRON PRO program, a 10-week strength journey that just launched today! It is available exclusively on the CGX app. This session is a 40-minute leg day workout focused on lower-body hypertrophy and strength.

Or if you would like to join me for days 2 to 50 of the IRON PRO program over the next 10 weeks as they are released, you can use the 14-day free trial to see if it's a good fit for you!

You can complete this workout anytime you like, when you fancy a good leg day!

Workout Details

You will notice I use various weights in the same exercise, e.g., for lunges: I warm up bodyweight, then use 2 × 15kg / 33lb dumbbells for one set, and increase to 2 × 25kg / 55lb dumbbells for the remaining three sets. You don’t need as many different weights — you can lift the same load each set.

Equipment:

• Dumbbells / Barbell / Kettlebell
• Chair / Bench for Staggered RDLs*
• Mat for cool down
• Wrist straps*
• Wedge*
*Optional

Caroline’s weights for reference:

• 2 × 25kg / 55lb dumbbells
• 1 × 20kg / 44lb dumbbell
• 2 × 15kg / 33lb dumbbells
• 2 × 10kg / 22lb dumbbells

Timer:

Most sets are 45 seconds long, followed by 60 seconds of rest. The timer is only a guide — you can finish early if you’ve completed your reps, or continue past the beep to finish your set.

Workout:

• Static Lunge – 4 sets (2 × 15kg for set 1, 2 × 25kg for remaining 3) → Switch side
• Heel Elevated Squats – 4 sets (2 × 15kg)
• Staggered RDL – 4 sets per side (progressing 15kg → 20kg → 25kg) → Switch side

Finisher:

• Front Foot Elevated Lunge – bodyweight only (both sides)
