Plank Challenge: 30 Days

Get a stronger core in just 30 days — no gym, no equipment, no excuses. The 30 Days Planking Challenge guides you from your very first 20-second hold all the way to a 10-minute plank with a progressive, day-by-day program you can do anywhere.

Hands-free voice coaching counts you in, calls the halfway mark, and pushes you through the final seconds — so you never have to look at your phone mid-plank. Just press start and hold.
