I have been really confused about exercise during quarantine. What are you guys doing to build muscle without equipment? I am too poor to buy weights. So it's a problem. It gets very expensive. Calisthenics dont feel like its enough. I'm really skinny. 5-7" and 110 pounds. I need weights to grow. I'm wondering if anyone came up with an idea or an alternative. All I have is a pull up bar, ab wheel, yoga mat and 2 - 15 pound dumb bells. I need heavier dumbells. But just cant really afford it. Thanks. I hope you are well and healthy and accomplishing your NoFap goal and fitness goals.
