Theoretical vs. Actual Network Speeds. The performance of Wi-Fi networks practically never approach these theoretical maximums. 802.11b networks, for example, generally operate no faster than about 50 percent of theoretical peak, around 5.5 Mbps. Likewise, 802.11a and 802.11g networks generally run no faster than 20 Mbps.
It is not unusual to see aerobic dance and Zumba, a form of dance to Latin music, offered in neighborhood gyms and community centers. Both have similarities but some differences for participants.
Generally speaking, Zumba classes last about an hour and are full of full-bodied, rapid dance moves choreographed specifically to get the body moving and the heart rate up. The amount of energy required to pull off an hour-long Zumba class makes it a great way to burn loads of calories and build lean muscle all over the body. The official Zumba website says that people burn âhundredsâ of calories during an hour-long Zumba workout, but that number leaves a huge range of calories and, while inspiring, might not be particularly helpful.
