CUTTING VS BULKING: WHICH ONE SHOULD YOU DO FIRST AND HOW TO KNOW

Cutting and bulking are terms that get thrown around constantly in fitness circles, and they confuse a lot of people who are trying to figure out where to start. The concepts themselves are simple. A bulk is a phase where you eat in a caloric surplus to support muscle growth. A cut is a phase where you eat in a caloric deficit to reduce body fat. The question is which one to do, in what order, and for how long.

The answer depends on where you are starting from.

IF YOU ARE NEW TO TRAINING

For people in their first year of consistent training, the cut-or-bulk question is mostly a distraction. Beginners are in a unique position where their bodies can build muscle and lose fat simultaneously, a phenomenon often called body recomposition. This happens because the training stimulus is novel enough to drive muscle growth even without a surplus, while a modest caloric intake can still support fat loss.

In practical terms: if you are new, eat around your maintenance calories with high protein, train consistently, and let your body adjust. You will likely see improvements in both body fat and muscle mass without having to pick a lane. Worry about formal cutting and bulking phases once you have a year or more of solid training behind you.

IF YOU HAVE SOME TRAINING HISTORY

Once you are past the beginner stage, your body needs a clearer signal. Muscle growth at this point requires meaningful progressive overload and, for most people, a modest caloric surplus. Fat loss requires a deficit. Trying to do both simultaneously becomes increasingly difficult.

The general recommendation for people at a healthy body fat percentage who want to add muscle is to spend time in a controlled surplus, roughly 200 to 300 calories above maintenance, with very high protein. This produces muscle growth with minimal fat gain. When body fat has crept up to a level that feels uncomfortable or that you want to address, move into a deficit phase.

For people who are carrying significant body fat and want to build muscle, losing fat first tends to produce better outcomes. Lower body fat improves insulin sensitivity, which supports muscle protein synthesis. It also makes you leaner before adding muscle, which means the end result of a subsequent bulk is visually more impactful.

HOW LONG EACH PHASE SHOULD LAST

Bulk phases typically run 3 to 6 months. Long enough to accumulate meaningful muscle growth, short enough that you do not gain excessive body fat. A well-managed bulk should not leave you feeling dramatically worse about your physique at the end of it.

Cut phases typically run 8 to 16 weeks. Longer than that and you run significant risk of muscle loss, hormonal disruption, and metabolic adaptation that makes further fat loss difficult. Aggressive cuts shorter than 8 weeks can work for specific situations but are harder to sustain and more likely to cause muscle loss.

THE MISTAKE MOST PEOPLE MAKE

Going too aggressive in both directions. A bulk that puts you in a 700 calorie surplus will produce fat gain that takes twice as long to reverse as the muscle you built. A cut that drops you 1,000 calories below maintenance will strip muscle along with fat and leave you smaller but not noticeably leaner proportionally.

Moderate is the operating principle in both phases. The goal is to make each phase productive and to transition between them at the right time, not to see how extreme you can go in either direction.

Working with a coach during these phases is genuinely valuable because the monitoring matters. Knowing when to transition, how to adjust protein targets as weight changes, and how to maintain training performance through a cut are details that are easy to get wrong and that significantly affect the result.
