One easy way to do a tricep workout using a lat pulldown machine. It must be a machine and not a weight/pulley system. Actually, it could be that as well but you would need a different attachment. Anyways, the pulldown machine will have to have a close grip and not just a wide one. All you need to do is stand on the seat, put your hands on top of the grips, push down, then step down to the ground. There ya have it, a tricep push down excercise. Thats just an improv tho, leave the appt and get to the gym!!!
