The Claim

In young males, ten weeks of periodized resistance training combined with a daily protein intake of 1.8 g/kg body weight and supervised training increases leg press 1RM strength by approximately 80–85 kg and bench press 1RM strength by 11–12 kg.

In plain English

If young guys lift weights in a structured way for 10 weeks, eat about 1.8 grams of protein per kilo of body weight every day, and have supervision, they can get way stronger—adding around 80–85 kg to their leg press and 11–12 kg to their bench press max lifts.

See the scientific wording

Ten weeks of periodized resistance training in young males increases leg press and bench press 1RM strength by approximately 80–85 kg and 11–12 kg respectively, when combined with a daily protein intake of 1.8 g/kg body weight and supervised training.

What the research says

1 study
  1. Study: Daytime and nighttime casein supplements similarly increase muscle size and strength in response to resistance training earlier in the day: a preliminary investigation

    The study looked at young men doing 10 weeks of weight training with high protein, and found their leg and chest strength increased by about the amounts claimed.
