These numbers are very low, for at least my region. Paver patios run about $20.00+ per square foot, higher for upper end pavers. That's patio install only, not including lawn repair, pergolas, columns, seat walls, lights, walls, steps etc... So figuring a flat yard and being able access with machinery. If by hand price goes up.
Aerobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process.
Anaerobic exercise is very high intensity or at your maximum level of exertion. Examples include sprinting and weight lifting. Consider using intervals, aerobic with some bursts of anaerobic exercise mixed in periodically to improve weight loss and overall fitness.
