Dumbbells and other home weights can help you build muscle fast – but so can bodyweight exercises. Take, for example, this 15-minute full-body workout. It exercises all major muscle groups; you only need a workout mat to avoid carpet burns. Since it's physical fitness we're talking about, you might also need some determination, of course, but we hope this goes without saying.
Bodyweight exercises have several benefits, including adjustability – there is often a more beginner-friendly version of the movement – convenience – you can do them anywhere, anytime, thanks to the lack of equipment used – and effectiveness. Harvard Health Publishing also mentions the low intimidation factor, its cost-effectiveness and the apparent health benefits of bodyweight movements. All in all, not a bad way to work out, no matter how skilled you are in fitness.
