The Isokinetic Home Leaper allows athletes to train fast to become fast with more explosiveness. Only with our Leaper athletes do 25-30 reps, do it in 30 seconds, get the exact amount of resistance they exert, automatically and with every rep as they fatigue, and do it safely, without the usual sore muscles resulting, do the training in less time. All athletes need to develop their white quick twitch muscle fibers and our Leapers excel with speed resistance training that is not possible with the usual weight training.
