Strength sessions 2-3 times a week if you want to see improvement, 1 a week to maintain is the general rule. If you're not well trained you'll still see improvements doing it once a week most likely. That's strength work, strength endurance work like pushups, sit ups etc. can be done most days without any problem. Unless you struggle to do 5 pushups, then pushups would be strength work. Bodybuilding is about volume of work so it's a lot of sub maximal lifting every day focusing on different body parts to let muscles groups repair while you work on something else. Bodybuilders have lots of hypertrophy of slow twitch fibres, to contract the largest fibres you do need to lift heavy as well so bodybuilders do also include some max strength work if they know what they're doing. That is taxing so they'll do it once or twice a week. Bodybuilders aren't strength athletes Ovee, they're in the gym everyday doing higher reps with lesser weight to really feel the burn, they take short rest breaks. You find a bodybuilder who doesn't train like that and he's not going to be too successful unless he has the best genetics and drugs.
Try reading this (I know it's difficult for you) - http://www.t-nation.com/free_online...raining_performance/stripped_down_hypertrophy Then read the 15 pages of replies and results from this routine by average guys - http://tnation.t-nation.com/free_on...ripped_down_hypertrophy_1?id=1929127&pageNo=0 If you want to argue they're all wrong about their muscle and strength gains go ahead, join the forum and get your arsed laughed out of there. Please do that, it'd be hilarious.
When I saw the list of trainers you mentioned, I was like "hrmmm, somebody's been to Testosterone Nation"... these links confirm it. Nice finds by the way. To answer the OP's question: I'm only lifting heavy once a week right now. I'm on pretty heavy calorie restriction & usually train 5 days a week. Besides having trouble finding time for an additional weight lifting session, my recovery is not what it once was (especially with the calorie restriction). For example, if I do weights and yoga on the same day, fatigue sets in and my form suffers on the weights, which has led to injuries. Also, lifting twice a week means I hit burnout faster - usually means a light week every month or two; with once a week I haven't hit that point yet. If you're looking for advice on how often you should train, I would start with the other posters' recommendations of 2 or 3 times a week and figure out what your body can handle. I'm old and worried more about losing weight, so I'd rather be under-trained, under-fed, & consistent than anything else.
Really? You've avoided every single question I've asked you. Did you go and read the article I gave a link to? I'm guessing not. You should, you'd learn something instead of being so unbelievably ignorant. BTW, calling me "kid" in a vain attempt to discredit me just makes you look like a *****. Haven't you noticed everybody has questioned or agreed with me and it's you who's being called a moron and told you're wrong. Think about that.
