So I'm a pretty skinny guy. I'm about 5'8" and weigh around 160-165 lbs. I am trying to do a little lifting but nothing too extreme. Honestly I dont really have time to do much working out but I feel like I should lift a couple times a week, just for something. Right now I do 50 pushups and 50 leg throws a day and lift free weights probably 2 to 3 times a week. Is this going to help at all or do I actually need to go all out to get anything significant?
