Short hard efforts with easy recovery in between, such as 30 seconds fast, 90 seconds slow.
Hypertrophy
Muscle growth.
Loaded carry
Walking while holding something heavy, like shopping bags or dumbbells.
Mobility
Moving your joints freely through their full range.
Creatine
A well-studied supplement that supports strength and muscle.
Omega-3 (EPA, DHA)
Healthy fats found mostly in oily fish such as salmon, herring and sardines.

The key differences

  • Israetel puts more of the week into strength: about 65% against 20%.
  • Brecka puts more of the week into aerobic base (zone 2): about 55% against 25%.
  • Brecka puts more of the week into mobility and stability: about 20% against 5%.
  • In plans in their style, both use 1-minute intervals for hard sessions.
  • We rate the evidence behind Israetel's protocol higher: solid, against mostly weak for Brecka.
  • Supplements that go into a plan: Brecka, omega-3 fish oil, creatine monohydrate; Israetel, none (food first). Prescription items and personal stacks stay out of every plan.
  • Only Brecka has a mobility or movement routine of their own.

Protocols side by side

Each line is rated for the evidence behind it. “Doctor only” items never go into a plan.

Training

Gary Brecka

  • About 30 minutes of low-intensity movement in the morning (part of the '30-30-30' idea he promotes)Strong evidence
  • Stay mobile and active every dayStrong evidence
  • Exercise while breathing extra oxygen (EWOT)Personal habit
  • Gives few specific strength-training targetsNote

Mike Israetel

  • For the average person, about 30 minutes of training twice a week gives the best return on time.Some evidence
  • After 40: most sets in the 10–20 rep range, some at 20–30, and 5–10 reps only rarely, because heavy low-rep sets raise the risk of injury.Some evidence
  • Train each muscle twice a week, starting with 1–2 hard sets per muscle per session, and add a set the next week if you recovered well.Some evidence
  • Lower the weight slowly and pause for 1–2 seconds at the bottom.Some evidence
  • Warm up more: three warm-up sets (light, medium, heavier) before the first working set, and 1–2 before each later exercise.Personal habit
  • Add weight in small steps: rarely more than about 2.5 kg or one rep per set at a time.Personal habit
  • Choose joint-friendly exercises with a high stimulus, for example a hack squat instead of a heavy back squat.Some evidence
  • Take a planned easy week every 4–6 weeks, and a lower-volume month about every 5 months.Personal habit

Eating

Gary Brecka

  • About 30 g of protein within 30 minutes of wakingSome evidence
  • Avoid processed foods; eat whole foodsStrong evidence
  • Lower-carb or ketogenic plans for weight loss in some clients, guided by blood testsDoctor only

Mike Israetel

  • If you want to gain muscle, only gain weight when you are lean: about 0.25 kg a week for 4–8 weeks, then a fat-loss phase.Personal habit
  • Stay under about 20% body fat while gaining, come back to about 15% afterwards, and get blood tests after gaining phases.Personal habit

Supplements

Gary Brecka

  • Vitamin D3, ideally guided by a blood testDoctor only
  • Omega-3 fish oil in the morningSome evidence
  • Methylfolate and methylated B vitamins based on a methylation gene testPersonal habit
  • Hydrogen water tabletsPersonal habit
  • Creatine (sold under his brand)Some evidence
  • Peptides such as BPC-157 and TB-500 (he is a fan)Doctor only

Mike Israetel

No specific guidance in what we reviewed.

Sleep & recovery

Gary Brecka

  • Morning daylight to set the body clockStrong evidence
  • Short daily cold water exposureSome evidence
  • Red light therapy bed, about 20 minutesPersonal habit
  • Hyperbaric oxygen and cryotherapy at homePersonal habit

Mike Israetel

No specific guidance in what we reviewed.

Stress & mind

Gary Brecka

  • Wim Hof-style breathing: 3 rounds of 5–30 breaths, then a breath hold, always seatedSome evidence
  • Same routine at the same time each dayPersonal habit
  • Barefoot grounding outdoorsPersonal habit

Mike Israetel

No specific guidance in what we reviewed.

Weak spots to know

Gary Brecka

  • He is not a medical doctor or a research scientist; McGill University's Office for Science and Society (Jonathan Jarry, 2025) called his expertise questionable and said the health interventions he points customers to run from unproven to pseudoscientific.
  • His MTHFR claims run against medical genetics guidance: the American College of Medical Genetics and Genomics has advised against routine MTHFR variant testing since 2013 (updated 2020).
  • Hydrogen water, grounding and red light are presented with more certainty than the research supports; the McGill review described hydrogen research as small and early, and grounding as pseudoscience.

Mike Israetel

  • Most of his content is aimed at bodybuilders and younger lifters; advice for people over 40 is a smaller part of it.
  • Many specific numbers, such as when to take easy weeks or how fast to add sets, are coaching rules of thumb rather than findings from trials.
  • He sells training programmes and diet products through RP, the company he co-founded.
