Lifting weights means discomfort for most of us. But with our cushy lives, we need to be uncomfortable more often. We need to push our limits from time to time to see what we are capable of. The benefits of lifting go beyond a strong and lean physique. Lifting heavy things teaches us who we are, how we handle difficulty and how we persevere. It builds our confidence and improves our self-esteem. In absence of regular physical challenges, we all need to push or pull heavy things now and then to test our boundaries.
