How to Make Your Planks Even More Effective
Planks are one of the most effective exercises because they fire up so many muscles at once, especially the core and upper body. You can make them even harder — you know you want to! — by adding a pair of dumbbells. Grab a pair of one- to five- kilograms and throw these moves into your next routine. Since plank position can be tough on the wrists, alternate these plank variations with moves that give your hands a break, such as squats or lunges.
