Can you workout the same routine everyday?

Cross directional training is probably the best approach you could do for your body. Your body becomes accustom to your workouts, there's no change therefore really no benefit except the caloric burn. Your muscles need to be constantly "fool" in other words and as always, you need adequate time for recovery. Muscle is nothing but scar tissue that has repair itself over recovery time. If your constantly blitzing your body, you in fact do more damage than good.

Often recommended that if you want muscles that are somewhat smaller but more cut and defined to work them out every day and it will also give you more endurance in those muscle groups. For brute strength and size take days off.

if you do the same exact routine, your body with get used to it.

Seperate the body groups.

Day 1 - Chest and Tri's
a. warm up
b. horizontal bench
c. incline bench
d. inverted bench
e. cable pulls
f. tri extention
g. cable push down.
Day 2 - Back then Bi's
a. work your back first, then your bi's. Because, your always using your biceps with your back muscles. So, if you exercise your biceps first, you'll over fatigue them and you won't have an effect back routine.
Day 3 - Shoulders
a. remember to work your rear delts
Day 4 - Legs
a. A lot of people look over their legs. But, strong legs are a foundation to a strong body.

Then repeat, or rest a day then repeat. You can do abs everyday. And try working the whole muscle group.
