LEAN AND ATHLETIC
How to get a lean athletic body
Train strength, aerobic fitness and speed every week for years: two or three strength days, one VO2max session of hard intervals, one functional session of full-body circuits and an easy run that ends in a few short hill sprints. If that is more than you can fit, the minimum is those hill sprints at the end of one easy run, next to your strength days. Food and sleep are the other half of the job. Complete starts from your long-term goals, such as build muscle, lose fat or become an athlete, counts every workout that reaches Apple Health and tells you what to do each day.
What lean and athletic ask of your training
Lean means a low amount of body fat for your frame. Athletic means you can lift, run, jump and keep going. Training builds the second one. The first one also depends on food, sleep and time, and this guide covers the training side.
An athletic body is trained on three fronts. Strength is how much you can lift. Your engine is your aerobic fitness, which is how long you can keep going at a steady effort and how fast you recover between hard efforts. Speed is how fast you can move and how well you handle hard bursts, in sprints or in a sport.
The weekly mix
Easy means a pace you could hold a conversation at, often called Zone 2. Hard means you are too out of breath to talk. A hill sprint is a short, all-out run uphill, 10 to 15 seconds, with a walk back down to recover. Do 6 to 8 of them at the end of an easy run.
VO2max is the most oxygen your body can use, the top of your aerobic engine. A VO2max session is hard intervals, for example 4 x 4 minutes hard with 3 minutes of easy jogging between. A functional session is a circuit of full-body moves such as carries, sled pushes, lunges, wall balls and rowing, the kind of work Hyrox races are built from. Hyrox is a race that alternates running with stations such as sled pushes, rowing and wall balls.
One way to lay it out: strength on Monday, an easy run that ends in hill sprints on Tuesday, the VO2max session on Wednesday, strength on Thursday, the functional session on Friday, easy long cardio on Saturday and rest on Sunday. Once that week feels routine, a third strength day can take Saturday’s place.
If six sessions is more than you can fit, start with four days: strength on Monday, an easy run with hill sprints on Tuesday, strength on Thursday and easy long cardio on Saturday. Add the functional session first, at its beginner size, then the VO2max session. Hill sprints load the knees, ankles and hips, so run your first ones at about 80 percent effort. If your legs are still heavy on Wednesday, do the 4 x 4 on a rower instead.
If you can fit only one piece of hard work beyond your lifting, make it the short hill sprints at the end of an easy run. They add little time to a run you already do, and they keep speed and leg power in your week.
| Piece | Each week | What and why |
|---|---|---|
| Strength | 2 to 3 sessions of 40 to 60 minutes | Heavy, full-body lifts build and keep muscle, which is the base of an athletic body. |
| VO2max | 1 session of about 40 minutes | Four hard efforts with easy jogging between them train the top of your aerobic engine. |
| Functional | 1 session of about 35 minutes | A circuit of running, rowing, lunges and wall balls trains your whole body to keep working when you are tired. |
| Speed | 6 to 8 hill sprints at the end of an easy run | Short uphill sprints of 10 to 15 seconds keep you springy and train fast leg drive. |
| Easy cardio | 1 to 2 sessions: an easy run and an easy long session | A walk, jog, ride or swim at conversation pace builds the aerobic base and helps you recover between hard days. The easy run is the one that ends in hill sprints. |
| Rest | 1 full rest day, plus sleep | Your body adapts to the work while you rest. |
How to look athletic, not bulky
People who say bulky picture bodybuilding volume: many sets for every muscle, trained for size, with plenty of food to match. An athletic week is a different mix. It uses fewer sets on the big lifts, such as squats, presses, rows and carries, and it adds the engine and speed work that a bodybuilding program leaves out.
In practice that means two to four hard sets per lift, in the 5 to 12 rep range, with a few minutes of rest between the heavy ones. Keep each strength session to about an hour. Then spend the rest of your week on easy cardio, hill sprints, the VO2max session and the functional session.
How big you get depends on your food, your genetics and how long you train, so no mix can promise a result. This one trains strength, endurance and speed.
A VO2max session from Complete’s workout library
This is the Norwegian 4 x 4 run: four hard efforts of 4 minutes, with 3 minutes of easy jogging between them. It takes about 40 minutes. Hard means effort 9 out of 10, so your breathing is heavy by the end of each effort, not in the first minute. Pace the first one so the last one is still strong. An A-skip is a quick skipping drill that primes the legs for fast running.
If you are new, jog the full 3 minutes every time. The win is the time you spend near your maximum heart rate, not your pace. If running pounds your legs, the library has the same 4 x 4 on an indoor erg machine such as a rower, the Erg Engine 4 x 4.
| Block | What you do |
|---|---|
| Warm-up | World’s Greatest Stretch (a lunge with a twist that opens the hips and upper back): 1 set of 4 reps per side. A-Skip: 20 meters. Run: 10 minutes at effort 3 out of 10. |
| Main: 4 rounds, 3 minutes of easy jogging between rounds | Run: 4 minutes at effort 9 out of 10. |
| Cool-down | Run: 5 minutes at effort 2 out of 10. |
A functional session from the library
The library’s Run + Stations AMRAP is a functional session of about 35 minutes. AMRAP means as many rounds as possible in a set time. You warm up with 5 minutes of easy running and the World’s Greatest Stretch for 4 reps per side. Then you work for 20 minutes, and each round is a 400-meter run at effort 7 out of 10, 10 calories on the rower at effort 8 out of 10, 10 sandbag lunges per side and 10 wall balls. A wall ball is a squat that throws a medicine ball at a target on a wall. A 5-minute easy jog closes the session.
Keep every round at about the same pace. Beginners cap the work at 15 minutes and use a 400-meter run, 6 calories on the rower, 6 lunges and 8 wall balls.
A strength day from Complete’s workout library
This is the Kettlebell Complex, four rounds of swings, squats, cleans and rows with a single kettlebell, finished with Turkish get-ups. It is full-body strength for one bell and a square meter of floor, and it takes about 40 minutes. Use it as one of your strength days.
A clean brings the bell from the floor up to your shoulder. A Turkish get-up is standing up from lying on the floor with the bell held overhead. Do the get-ups slow and deliberate, with your eyes on the bell, and own every position.
| Block | What you do |
|---|---|
| Warm-up | World’s Greatest Stretch: 1 set of 4 reps per side. Kettlebell Swing: 1 set of 10 reps with a light bell. |
| Main: 4 rounds, 120 seconds rest between rounds | Kettlebell Swing: 15 reps. Goblet Squat: 12 reps. Kettlebell Clean: 8 reps per side. Gorilla Row: 10 reps per side. |
| Finisher | Turkish Get-Up: 2 sets of 3 reps per side, 90 seconds rest. |
Choosing the weight
If you are new to kettlebells, use a 12 to 16 kg bell and do the get-ups without the bell until the path is smooth. The standard version is the four rounds above with a 16 to 24 kg bell. If you are experienced, use a 24 to 32 kg bell and keep each round unbroken, with no stopping inside a round. Pick the weight by the clean: if the catch is loud, go lighter.
How Complete fits a lean, athletic lifestyle
Complete starts from your long-term goals, and for this look the ones that fit are build muscle, lose fat and become an athlete. They steer what it recommends every day, with or without a plan.
It knows you. Complete reads your goals, your history and your recent training load. If you wear a watch that records HRV and resting heart rate, it scores your recovery against your own baseline once it has about a week of data. HRV is the small variation in time between heartbeats. Over time the daily recommendation gets to know your body, your schedule and the sports you play.
The Coach adapts to you. It sees your recovery and can suggest an easier day, and you decide, which helps in a week with a VO2max session in it. If you have a plan, the Coach proposes changes and you choose to apply them to your week or keep it as it is.
Frequently asked questions
How do I look athletic and not bulky?
Train a mix: two or three strength days with a few hard sets per lift, a VO2max session, a functional session and an easy run that ends in hill sprints. That is far from bodybuilding volume. How big you get also depends on your food, your genetics and time, so the mix makes no promise about your result.
How many days a week should I train for a lean, athletic body?
Six sessions in the week above, with one rest day. If that is too much, start with four days: two strength days, an easy run that ends in hill sprints and easy long cardio. If you can fit only one piece of hard work beyond your lifting, make it the hill sprints.
How heavy should I lift?
Heavy enough that the last rep of each set is hard and your form still holds. In the kettlebell session above, pick the bell by the clean: if the catch is loud, go lighter.
What is the best app for a lean, athletic lifestyle?
Pick one that covers more than the gym, because this week mixes lifting, running and rowing. Complete counts every workout that reaches Apple Health from any watch and builds its daily recommendation from your goals and recovery, with or without a plan.
Does food matter for a lean look?
Yes. Training builds the muscle that shapes the look, and the fat over it comes off only when you eat less energy than you burn. This guide covers the training side, and the look guide linked below covers food.
