In this video I trained like Chris Bumstead for 7 Days to see if I could make progress cutting fat while maintaining muscle. Recently, I have been trying to bulk up, and got to the point where i wanted to shred some body fat. So I decided to try Chris Bumstead's insane shredding diet and training routine to see how I did. Chris Bumstead is 3x Mr. Olympia, and has an absolutely incredible physique and work ethic. Here's how I did with his training.

Have a great week guys! Cheers.

7 days is too short of a time frame for anything

[viksenpai]

Hey Cam,

I'd like to point out some aspects, that might help in the future.
1. You mentioned 1600 calories, but this seems too low for C-Bum even in peak week, so I'm assuming you've scaled this to your own weight. If not - keep in mind 2 things - Chris's maintenance is around 3500 kcal, while yours is likely around 2500, given the difference in weight and muscle mass. Second, as you said, Chris DOES NOT sustain such a diet for weeks, this is likely peak week level of restriction.
2. The training modalities of beginner, intermediate and advanced people vary greatly. A "bro-split", i.e. every part has it's own day, or something similar is WAY LESS EFFECTIVE for beginners or intermediate lifters in comparison to other popular splits like PPL or UL (or even 3x Full Body). This much of a focus and resting times between sessions for the same muscle group is required for people with huge amounts of muscle, since they need so much volume and thus, recovery to grow that anything less might be insufficient.

All in all, although a fun willpower experiment, there is nothing to gain from such competition level types of restriction and training splits, you're far better off cutting for 6-14 weeks at a time, with a stable(-ish, you might need to auto-regulate) ~500 calories deficit and a good beginner or intermediate split.

Cheers!

The video isn’t called “following the best most optimal fat loss diet” he’s following CHRIS BUMSTEADS routine. He did exactly what he said he was going to😂

[silkebuechel]

The „too slow” remark after the “skip ad” cracked me up way too much 😂😂

[BUTLProductions]

The steroid injection cutaway was hilarious!

[levipatrickdiaz]

Isn’t it more reasonable to assume that most of the weight loss was water though? Isn’t that typical at the beginning of a calorie deficit? Especially if your cutting diet had less sodium and you also upped your activity levels. I feel like this kind of challenge could be more effective if done for a longer time. To me, at least a month is necessary to notice a reasonable amount of change from a shift in diet or exercise. At one week, there’s all sorts of factors that could make a person lose more or less weight than expected

7 days is way to short for comp differences, there are also different parameters like holding on to water. 14 days is a pretty good time to weigh in in general

[steggy]

Chris doesn't do this diet for months though, he only drops to that low calories right in the week or so lead up to Mr Olympia.

8:58 Wtf this is Mt Pleasant in Vancouver :O

This video was hilariously made. Thanks! Also it's motivating to see people stick to certain goals and habits for even short periods of time.

[jaybrian__]

Love the content keep grinding brotha ❤ I know this was an old content but just came across this!

[marksaldanha]

Was so confused when I saw the ad countdown timer at 5:25 since I have YouTube premium 😂😂

[kristidaemon]

Thank you for the video and a "torture" that you endured :D I don't know why many people in the comments are talking about results and that it takes months. The video is clearly states that it is to see what happens in a week with this routine for a beginner user and it shows exactly that. It wasn't made to see if Chris's shape could be achieved, it was to try how hard it would be and there are results: constipation, carbs withdraw, weight loss (with muscles and not only fat). I think video delivered exactly what it promised. Thank you again! No-one, except professionals, should try to do it for a month or more.

hahaha the steroid joke was hilarious AF had me laughing at my phone

[hover_roller_balance_boards]

Gotta try the hover roller training program. It’s beast 💯👊🏽

This video is full of misinformation regarding how fat loss works. For one as everyone else has already pointed out, the amount of weight your losing is mostly water weight. The water weight loss mostly resulting from less carbs - less glycogen, and glycogen stores 3 times it's weight in water, this is why if you significantly cut your intake it seems like you drop a bunch of weight magically, because it's all mostly water weight. The other huge issue there is the time frame. 7 days is nowhere near enough time to have any significant fat loss, even if you were eating 0 calories and burning as many as you normally would, which obviously is very difficult since you're depriving yourself of all your energy and relying purely on slow acting fat stores for energy. Going purely based off the roughly 1k calorie deficit you were in, you at most lost 2 pounts of fat this week. This needed to be extended too around 2-3 weeks for significant fatloss to occur. Another way to make this better would be to scale it appropriately for you. 1600 calories is a 3500+ calorie deficit for Cbum but is less than half of that for you, combine that with him doing that for around month to prep for shows and ofc he's going to be absolutely peeled on stage.

Cam, you can do better

From what I know he isn't doing 5 day workouts, but 6 workouts:
Legs (Quad focused)
Chest
Back
Legs (Hamstring focused)
Shoulders
Arms
Idk if it's in that order, but if it would be mine this is how I would put it.

[killab]

The lowered carbs means you will not retain as much water. This will lower your weight in the first few days. You’re not losing much fat and no muscle within 7 days. This should have been at least 30 days.

[carlossaavedra]

but that low calorie intake mught be just before competion not on regular basis or am i wrong?

[carlvanlife]

I would love to see you guys try out 3 months of Elliott Hulses diet & workout routines (lean bulk)
