Five moves and 20 minutes are all you need to improve core strength at home without weights. Sure, lifting heavy in the gym has plenty of benefits (building strength, muscle mass, stability and power, to name a few), but you don't always need heavy weights for a powerful core workout.

Grab a yoga block and give these five moves a try. It’s perfect for beginners or anyone without weights at home. If you don't have a block, use a book instead. And I recommend the best yoga mats for support. Let's do this.
