any advise?

hi guys pretty new to this but really want to achieve my goals which are to lose some weight i weigh 13stone 4 pounds im 5ft 10 and should be bout 11stone apparently. i want bigger arms, tone my stomach, bigger pecs
 
i have been experimenting with different equipment but here is what i did today
 
15 mins on bike
15 mins on ski machine (well thats wot i call it)
10 mins fat burning program on tread mill
bicep exercise pull down 25kg 4 sets of 10
pec deck 25kg 4 sets of 10
ab crunch 20kg 4 sets of 10
 
not had my weight training induction but i heard cross wire and bench press are good for buidling my pecs as the pec deck is what gives u the definition or the line down the middle of your chest...
 
any suggestions also i have bought some whey protien is twice a day sufficient using it been eating loads of salad and meat
 
any help would be appreciated

Listen to cpl, he knows what hes talking about

It's impossible to meddle with something that doesn't have a plan

thanks guys, its weird cos im only 32 waist and 38 chest but i know i need to shift a layer of fat for sure and maybe on the legs and butt found that post from cpl really helpful about working the ower back and legs more to avoid injury and have decided tomorrow on my induction i want an overall work out on my muscle including upper lower back shoulders and legs not just the chest,abs and arms thanks
