Look up any phone number and get the answers you are looking for! Wish I would have had this over 2 years ago, I could have divorced sooner. I busted my ex with her boss using this. I found out my boyfriend was still using drugs with this. So to all you idiots hating, this could be saving lives.
Open kinetic chain exercises (OKC) or open chain exercises are exercises that are performed where the hand or foot is free to move. The opposite of OKC are closed kinetic chain exercises (CKC). Both are effective for strengthening and rehabilitation objectives.
Isometric exercise or isometrics are a type of strength training in which the joint angle and muscle length do not change during contraction (compared to concentric or eccentric contractions, called dynamic/isotonic movements). Isometrics are done in static positions, rather than being dynamic through a range of motion.
