Building Muscle 101 | Training Splits/Intensity, Diet, Recovery

Summary

Muscle building depends on three main factors: nutrition, training, and recovery. The presenter’s central advice is to choose a sustainable routine, track your progress, and stick with it consistently over time.

Nutrition

• Take front, side, and back photos to assess your starting point.
• Track calories at first to understand how much energy foods contain.
• Estimate your maintenance calories using a TDEE calculator, entering your age, height, weight, and activity level. The presenter suggests aiming for about 10,000 steps a day.
• For adults seeking to lose fat, he recommends starting about 500 calories below maintenance. For people who are already lean, he suggests a small surplus of 100–150 calories to support muscle gain.
• Weigh yourself daily. If your weight is changing too quickly or moving in the wrong direction, adjust your intake in 100-calorie increments.
• Aim for 0.8–1 gram of protein per pound of body weight and 0.3–0.5 grams of fat per pound. The presenter suggests aiming for the lower end of each range during a calorie deficit. Use carbohydrates to fill the remaining calories.

Training

Choose a training split that fits your schedule and that you enjoy. The presenter says the specific split matters less than consistency and effort. Options he describes include:

• Six days: Push/pull/legs, repeated twice.
• Six days: An Arnold-style split, such as chest/back, arms, and legs, repeated.
• Five days: Push, pull, legs, rest, upper, lower, rest.
• Four days: Upper, lower, rest, upper, lower.
• Two or three days: Full-body sessions.

Start with a manageable amount of work—about one set per exercise—and monitor your recovery and performance. Record your workouts and keep your technique consistent. Use instructional videos or a coach to check your form.

Make the lifting portion of each rep as forceful as possible while maintaining good technique. The presenter recommends working close to failure; beginners can use sets to learn what failure feels like.

Use a rep range and progress gradually. He prefers 5–9 reps, while 8–12 reps is an option for beginners practicing technique. Add weight once you can reach the top of your chosen range with consistent form.

Recovery

Aim for 7–9 hours of sleep per night, with eight hours as the presenter’s ideal. He also recommends following your nutrition plan, drinking about four liters of water, and allowing enough recovery between workouts.

The presenter argues that sleep and consistent training and nutrition matter more than relying on saunas, ice baths, or other recovery practices.
