Forget crunches! Build your strongest core ever with 100 Planks! It includes 100 of my all-time favorite plank variations with lots of tips for beginners, correcting movement patterns, planks for weight loss, preventing back injuries, and much more. I've been teaching abs classes for nearly 20 years so I've had a lot of time to see what works, what doesn't, and what lights up the eyes of my participants as they strive for goals they didn't even know they wanted to achieve. Also included are sample plans of where to start as a beginner, and standing modifications and tips on wrist health for those who have trouble being on the floor. All planks are assigned levels 1-4 to help you choose wisely and progress safely. When you purchase the book, you'll also get access to video tutorials on all 100 planks and more!
