Ok, so you may have already heard of ‘the plank’ – it’s an easy exercise often used to strengthen the core muscles and tone up tummies, and the idea is to stay in the plank position for as long as possible for the maximum benefit. One of the best things about the humble plank is that it’s absolutely free to do – from the comfort of your living room! The plank is one of the best exercises to strengthen your core, which is more than just your abdominals. The core is a complex series of muscles that includes your entire body, minus your legs, head and arms. Various plank exercises challenge all the major muscle groups and stabilizers, improve strength, and prevent injury. Many people choose to do the plank exercise because they want to build a more defined six-pack, and there’s no doubt that this exercise will certainly help in that regard, particularly if you are combining it with other abs exercises, and doing plenty of cardio to burn off any excess fat. Our plank challenges can help you achieve great things in a short space of time because you always have a specific goal that you have to achieve every day as it gets progressively harder.
