i think the two often go hand in hand. If you can squat 135 and bench 115 and in 5 months you can squat 245 and bench 185, are you going to look the same as you did 5 months prior?
No.. you will be bigger and stronger- diet will determine how big though
You can do both. You just need to be more down the middle with your training. I change my training in late fall and go for strength work outs then in the spring I go to a more looks work out. I also watch my % body fat during the warmer months, winter not so much. A disclaimer, I'm fine with 12-13% BF. Not really worth it to me to get really ripped. Winter time I head up to around 18.
