Froggie, U really need to get a good lifting routine. Even if u were doing the optimum weight, your current "workout" wont get you anywhere.
If u want a goodworkoutroutine, here is a good base to use
Each day, do one of your core lifts(Squats, deadlifts, powercleans, and bench)For the fith day, you could pick a lift that targets other large muscle groups such as lat pull downs, rows, etc. Those core lifts will work everything, and i mean everything, as well, even better than targetting each little single one joint muscles. It wont tak nearly as long eihter. These lifts should be the base of your workout, and you should put the most effort into these. If u want, you can add a couple auxillary lifts to each days workout, to furthur work desired muscle groups.
