Bodybuilders and physique composition consultants usually advise in opposition to bulking (sustaining a calorie surplus) except you’re already lean.
I’ve been considered one of them—within the first version of my e-book Larger Leaner Stronger (2012), I advisable males begin a bulking part round 10 p.c physique fats and ladies at round 20 p.c.
So, if a man was at 17 p.c physique fats, I used to be telling him to chop right down to round 10 p.c earlier than bulking. And if a gal was within the mid- or high-twenties, I used to be telling her to get to round 20 p.c earlier than attempting to maximise muscle and energy achieve.
Is that recommendation nonetheless sound? Is it nonetheless supported by the load of the proof? For probably the most half, sure, however not for a similar causes I initially thought.
Again then, I defined that starting a bulking part with low physique fats ranges had three predominant advantages:
You’ll be able to bulk for longer earlier than needing to cease as a result of extreme fats achieve.
Put up-bulk cuts are shorter since there’s much less fats to lose to get again to a super “upkeep physique.”
Being lean led to larger muscle features as a result of our physique’s “muscle-building equipment” labored higher after we have been leaner.
As we speak, my stance on the primary two factors stays the identical, however the third not passes muster. It appears that evidently having decrease physique fats (10-to-15% in males and 20-to-25% in girls) doesn’t considerably influence muscle development charges. To place it merely, in case your predominant aim is constructing muscle and energy, you’re in all probability by no means “too fats” to bulk.
I’ll spare you the technical particulars of why the “lean individuals achieve muscle quicker” speculation didn’t pan out, however the abstract seems like this:
A sequence of research carried out within the Nineteen Seventies and Nineteen Eighties on weight achieve discovered that when individuals with excessive physique fats ranges gained weight, it was largely fats, whereas when individuals with low physique fats ranges gained weight, it was largely muscle. Finally, evidence-based health consultants stumbled upon this analysis and speculated that the identical precept would possibly apply to bodybuilding—and that’s how the thought took root.
Nevertheless, the rub is that these research didn’t contain resistance coaching and infrequently included individuals recovering from anorexia, who have been severely under-muscled. This was uncovered in a later overview of the information that confirmed that when the anorexia research have been excluded from the evaluation, physique fats ranges didn’t appear to affect the ratio of muscle to fats achieve.
There’s nonetheless an ongoing debate about whether or not physique fats can meaningfully have an effect on muscle development, I’m not satisfied it’s a major issue. That mentioned, I lean towards the place that our physiology is probably going most “anabolic” at an athletic physique composition (one thing in between “shredded” and “fats”).
So what are the numerous elements?
Sustaining a gentle calorie surplus (about 10% above your complete every day power expenditure)
Consuming sufficient protein (0.8 to 1 gram per pound of physique weight every day)
Following a well-designed coaching program that progressively overloads your muscle groups
Prioritizing relaxation and restoration (getting sufficient sleep, taking relaxation days, deloading commonly, limiting cardio, and so on.)
Whereas I nonetheless advocate getting lean earlier than bulking for the explanations talked about (longer, extra productive bulks and shorter, simpler cuts), my steering now comes with a caveat:
In the event you’d slightly bulk now and minimize later—possibly since you really feel “skinny fats” or are simply excited to eat large and practice laborious—go for it. You received’t be held again by any so-called “anti-anabolic” limitations.
