Power lifting can quickly become anaerobic, when you  run out of oxygen.  But, weightlifting is used for more than just peak power.  Many activity&#x27;s benefit from pure strength, but most people are trying to improve both  power and endurance.<p>Longer cool down periods (3-5 min) helps build strength faster and let&#x27;s each set be more anaerobic and higher weight, but short cool down periods and slightly lower weight adds endurance and strength, plus more repetition.<p>The other benefit of aerobic weightlifting is you can better learn to minimize anaerobic activity.  Full power all the time seems great, but being dead on your feet in 30 minutes is rarely useful.
