Resistance Training, Nutrition, and Energy Balance

Movement Patterns

Exercise selection can be organized first by joint action and force direction rather than by machine name. Common patterns include chest press, chest fly, pulldown, row, overhead press, front raise, lateral raise, rear-delt fly, curl, triceps extension, squat, and leg extension or flexion.

Difficulty and Substitution

Exercise difficulty can be ranked by stability demand, free-weight involvement, path-control demand, and loading potential. Machine movements are usually easier to stabilize. Free-weight compound lifts usually require more technique and body control.

Training Splits and Frequency

A training split defines how the body's muscle groups are distributed across training days. Splits are typically selected by the number of available weekly training days, the per-muscle training frequency, and the volume of a single session. Common splits range from full-body to a five-way split, with per-muscle weekly frequency shifting as the number of training days changes.

A single session can use large muscle groups first and smaller groups as accessories. Large muscle groups often receive three to four exercises, while smaller groups often receive about two. A leg session can include seated leg extension, barbell free squat, leg press, prone leg curl, and seated hip abduction. A shoulder session can include standing barbell press, bent-over dumbbell lateral raise, bent-over dumbbell fly, and cable lateral raise. An upper-chest session can include forward-leaning band press, incline dumbbell press, flat dumbbell press, and cable cross fly. An upper-back session can include incline dumbbell row, seated pulldown, dumbbell row, and face pull.

Volume, Intensity, and Progressive Overload

A split determines how exercises are distributed, but training outcomes are driven mainly by volume, intensity, and how load is increased over time. These variables affect long-term adaptation more than the specific equipment chosen.

Progressive Overload

Progressive overload is the gradual increase of training stimulus over time and is the core mechanism for continued adaptation. Common methods include double progression (adding reps at a fixed load, then increasing load once a rep ceiling is reached), adding sets, shortening rest, raising frequency, and improving range of motion and control. Records need load, repetitions, and sets together so that progression can be assessed.

Load and volume can be organized through periodization. Linear periodization raises intensity and lowers volume across weeks; daily undulating periodization (DUP) alternates strength, hypertrophy, and endurance ranges within a week. After accumulating several weeks of training, a deload week with reduced volume or intensity is often scheduled to support recovery and limit accumulated fatigue.

Recovery and Training Frequency

Muscular adaptation occurs during recovery between sessions rather than during training itself. Recovery-related factors include sleep duration and quality, total energy and protein intake, and the accumulation of training volume and central-nervous-system fatigue.

Training frequency is how often each muscle group is stimulated per week. At equal total volume, training a muscle twice per week is generally not inferior to, and often outperforms, once per week in research. Splits that train each large group once per week (such as a body-part five-way split or a "chest / shoulders / back / legs" four-way split) concentrate a muscle's full weekly volume into a single session; when volume requirements are higher, the same volume can also be distributed across two weekly sessions by raising frequency.

Food and Nutrition Structure

Food records can be grouped by carbohydrate, fat, vitamins, trace elements, and protein sources. Carbohydrate sources include oats and quinoa. Free-sugar sources include honey and juice, with a recorded intake target of zero. Fat sources can be grouped by fatty-acid type: trans-fat intake can be set to zero; saturated-fat sources include animal fat, butter, and palm oil; monounsaturated-fat sources include olive oil, avocado oil, and hazelnuts; omega-3 polyunsaturated-fat sources include flaxseed, chia seed, and walnuts.

Fish selection can be organized by mercury exposure. Better choices include carp, Atlantic croaker, Atlantic cod, black sea bass, bream, catfish, clams, cod, crab, crayfish, flounder, haddock, hake, herring, lobster, mullet, oyster, Pacific chub mackerel, perch, pollock, salmon, sardine, scallop, shrimp, skate, sole, squid, tilapia, trout, canned light tuna, and whitefish. Good choices include amberjack, buffalo fish, Chilean sea bass or Patagonian toothfish, grouper, halibut, mahi-mahi, monkfish, rockfish, sablefish, sheepshead, snapper, Spanish mackerel, striped bass, tilefish from the Atlantic, yellowfin tuna, and weakfish or sea trout. High-mercury fish to avoid include king mackerel, marlin, orange roughy, shark, swordfish, tilefish from the Gulf of Mexico, and bigeye tuna.

Meal-Prep Structure

A breakfast structure can include carbohydrate, protein, fat, and vitamin sources. One overnight-oats formula contains milk 200 g, protein powder 1 scoop, oats 40 g, chia seeds 10 g, nuts and dried fruit 20 g, cocoa powder 10 g, and Greek yogurt 50 g.

Energy Balance

Energy balance is the relationship between energy intake and energy expenditure and is the overall determinant of changes in body weight and composition. Macronutrient allocation is built on top of a total-calorie target, so calorie estimation usually precedes macronutrient calculation.

Rate of weight change serves as a reference for whether energy balance matches the goal. A common rate of gain during a muscle-gain phase is about 0.25%-0.5% of body weight per week, and during fat loss about 0.5%-1% per week. Adipose tissue has an energy density of about 7700 kcal/kg, which can convert a cumulative calorie difference into an approximate weight change. Actual expenditure varies between individuals, so estimates usually require adjustment based on weight and circumference trends over several weeks.

Macronutrient Calculation

The recorded calculation method starts from total energy intake, then assigns carbohydrate and protein before deriving fat from remaining calories.

Supplements and Micronutrients

Supplements are used to fill nutrients that are hard to obtain adequately from diet or to provide performance ingredients with research support. Their role rests on total calories and macronutrients already being met.
