climb a 10 story building every day using the stairs. lol jk, but yea climbing stairs is one of the best exercises to do for your legs, climb up on a elliptical for about an hour or so a day and you should see the increase in your hops you are looking for...oh and also jump rope
Go for walks or even runs each morning for around 3 times a week. Do squats, run up the stairs and walk back down 20 times a day. You will see results quick enough
