Pumping iron might be effective in gaining strength and bulking up but not everyone likes to use weights for training. Some might be intimidated by them. Others may simply find them too large, cumbersome, or inconvenient. Fortunately, there are other ways to achieve fitness.
Consider the use of resistance bands which are usually rubber-based bands of different widths. They come in loops and in straight lines. They provide resistance when you pull on them. Use a narrow band for less load and a wider band for greater difficulty as you gain strength.
You can achieve a total body resistance band transformation at home. Check out different ways to develop your arms, legs, and core.
