Welcome to March! This month's challenge is called 'Muscle-up March.' Challenge yourself to improve your strength this month. By focusing on your physical strength you also improve many other aspects of your health as well. Jeff encourages you to explore within your limits. Notice how strength improves 'flow' state and makes the daily activities of living so much easier - things like climbing stairs without losing your breath, having the energy to walk further, and the ability to do more of the things you love!
