dont workout everyday its no good you need to give your body restign time figure it like this... when you do a bench press your stretching and tearing your shoulder muscle then when you sleep and recover your body rebuilds it but bigger just in case you do it again and it keeps growing due to that... now if you work out every day your body will keep deteriorating rather than building.. so when you work upper body rest for 2 days and you can work out your legs the next day but make sure you give them time too... just make sure you dont work out the same areas every day!!! you wont last long if you do that every day
