Warm up for core: 7 minutes before ab work or heavy lifts

Do 2 minutes of high knees, 5 walkouts and 20 seconds of bear crawl forward and back, then 8 dead bugs per side, a 20-second side plank each side and 8 Pallof presses per side. That is about 7 minutes. Before a heavy squat, follow it with 3 to 4 climbing ramp-up sets of the squat.

  1. High Knees Quads
  2. Walkout Abs, Shoulders, Chest
  3. Bear Crawl Abs, Shoulders
  4. Dead Bug Abs
  5. Side Plank Abs
  6. Pallof Press Abs

Raise: 2 minutes

Cardio that lifts the knees makes the abs and hip flexors work from the start.

Raise: cardio that also lifts the hips

High Knees

Quads

Lifting the knees to hip height makes the lower abs and hip flexors work while your heart rate climbs.

How to do it

  1. Stand tall and start jogging on the spot.
  2. Drive each knee to about hip height while the arms pump.
  3. Land softly under your hips and keep your chest up.

Cues

  • Knees up, chest up
  • Fast, light feet

Common mistakes

  • Leaning back to lift the knees: stay tall and lower the height if needed.

Raise: cardio from a plank

Mountain Climber

Abs

Running in a plank raises your heart rate and starts the brace at the same time.

  3. Keep your back flat and hips low, then crawl backward.

Put them together: example sessions

Each session below picks from the exercises above for one situation, with the sets, reps, rest and RIR filled in. Open one in the session builder to change a pick, price it from a recent set, and add it to RIRLift.

Session 1

  • EquipmentAdjustable Cable, Pull-Up Bar, Ab Wheel

You have a gym ab session with hanging raises and rollouts.

The warm-up covers front, side and rotation lightly, so the first hard ab exercise starts with a trunk that already knows how to brace.

Session 2

Before heavy squats

Open in the session builder
  • Workouts2× a week
  • Working sets14 a week
  • Per workout~20 min
  • EquipmentBarbells

Your session opens with a heavy back squat.

A brace that is switched on before the bar is on your back helps the first ramp set feel solid. The trunk drills stay short so your legs don't tire, and the squat gets four ramp-up sets.
