Build Muscle: Train First, Then Feed It

Stuart Phillips debunks the biggest muscle myth: protein alone doesn't build muscle, resistance training is the trigger that makes it grow. In his brick-wall picture, training builds and protein is just the bricks; without lifting 2 to 4 times a week, extra protein piles up unused, which matters most as you age and need to protect strength and independence.

Resistance exercise switches on muscle protein synthesis and keeps it elevated for up to a day afterward.
The protocol
2 to 4x a week
Do resistance training, no exceptions Lift weights or do hard bodyweight work 2 to 4 times a week. This is the part you cannot skip if you want muscle.

Training is the actual trigger for building muscle. Nothing you eat replaces it.

Phillips, resistance exercise research
Progress
Gradually make it harder Add weight, reps or difficulty over time so your muscles keep being challenged.

Muscle grows in response to a rising challenge, not the same easy routine.

Phillips, muscle research
Feed it
Have enough protein around your training Hit your daily protein target (about 1.2 to 1.6 g per kilo) and include some protein in the meals around your workouts, roughly 20 to 40 grams.

Once training flips the switch, protein is the material your body uses to rebuild.

Macnaughton et al., 2016
For life
Keep training as you get older Do not stop lifting with age. Keeping muscle is some of the best insurance you have for staying strong and independent.

Muscle loss speeds up with age, and resistance training is the proven way to slow or reverse it.

McLeod, Stokes & Phillips, 2019
Don't
Do not rely on supplements to do the work Powders and shakes are just convenient food. They do not build muscle without the training and total protein behind them.

Phillips is clear that supplements are optional convenience, not the cause of results.
