Practising skipping is dead simple: you can skip inside, in a park, on the beach, you can keep the rope in your bag, it can follow you everywhere. To skip you don't need any bizarre equipment, except the rope obviously, and you can easily find this for less than £10. At the beginning, it's best to go gradually…and start doing it every other day. Try to keep it up for a minute without stopping, then build in one minute of jumping, one minute of rest, one minute of jumping. Following this, crank it up to two minutes and reduce the rest period. For example, jump for two minutes and then have a 20 second rest between the two phases. Don't forget to stretch your calf muscles at the end of your session to avoid any soreness the next day!
