Fire up your core with some funky plank variations in this 30-minute workout. Natalie will get you to work primarily on those mid-section muscles in the first half, before bringing in some glute exercises in block 3 and back exercises in block 4. You’ll spend 45 seconds on each exercise, before taking a short break and moving on to the next one:

Block 1 – dead bug crunches to low plank, commando holds and bolt plank with two stomps
Block 2 – squat rotations, side plank rotations and kick throughs
Block 3 – fire hydrant side pulses and standing knee drives
Block 4 – lying pull down, 3-way leg drop and scissor kicks.
