Hold a plank every day for 30 days and log your streak.
Day 1: Plank Basics
Hold a standard forearm plank for as long as you can. Focus on keeping your hips level and your core braced — this is the baseline you'll try to beat over the next 30 days.
Day 10: Side Plank Challenge
Switch it up with a side plank on each side. Keep your body in a straight line from head to heel and resist the urge to let your hips sag.
Day 30: Plank Finale
The last stretch! Go for your longest hold yet and log how far you've come since Day 1.
