A good workout plan should not feel random. When you follow the best workout regimen for your goals, you know exactly why you are in the gym, how many sets and reps you will do, and how that effort moves you closer to more strength, more muscle, or less fat. Instead of guessing, you follow a clear structure that tells your body to grow stronger week after week.
Below, you will find a straightforward guide to building strength with well planned routines for beginners, intermediates, advanced lifters, and men over 40. You will also see how cardio, recovery, and nutrition fit into the picture so you can stay consistent and avoid burnout.
What makes the best workout regimen?
The best workout regimen for building strength has a few things in common, no matter your age or experience level. It respects your current fitness, pushes you just enough, and gives you enough rest so you can come back stronger.
A smart plan will:
- Use strength training as the foundation so you build or maintain muscle
- Include enough volume, that is sets, reps, and weight, to challenge your muscles
- Increase that volume gradually using progressive overload so your body keeps adapting
- Mix in cardio in a way that supports fat loss and heart health without draining you
- Allow for rest days and lighter sessions so you avoid overuse injuries
You can think of your regimen as a structure. Strength training forms the base, cardio sits on top, and recovery holds everything together. If one piece is missing, progress slows down.
Beginner strength regimen: Your first 8 to 12 weeks
If you are new to lifting, or returning after a long break, your best workout regimen is simple and repeatable. Your main job is to learn good form, build confidence, and create a habit.
Weekly structure for beginners
Begin with 3 full body workouts per week. For example, you might train on Monday, Wednesday, and Friday. This gives you a full day of rest between sessions, which is especially helpful when your muscles are learning to handle new loads.
Most beginner routines use:
- 3 full body sessions per week
- 3 to 4 sets of 8 to 12 reps per exercise
- 90 to 180 seconds rest for big lifts
- 60 to 90 seconds rest for smaller, accessory moves
These ranges are enough to stimulate muscle growth and strength without overwhelming your joints and nervous system.
Exercise selection and progression
Focus on compound moves that use several joints and muscles at the same time. Think squats, presses, rows, and pulls. You can use free weights or machines. Machines give you a guided path and are often easier to learn, while free weights ask more from your stabilizer muscles and core, which can lead to bigger strength gains over time.
Start with a weight that feels challenging in the last 2 to 3 reps of your set, but not so heavy that your form breaks down. Each week, try to make a small change:
- Add a little weight
- Add one rep per set
- Add one extra set on one exercise
This gradual increase is called progressive overload. It is one of the most important principles for muscle growth and strength, because it forces your body to adapt in a controlled way.
Intermediate regimen: Moving to 4 days per week
Once you have 6 to 12 months of consistent training behind you, a 3 day full body plan may not challenge you enough. At this stage, the best workout regimen usually shifts to 4 training days with more total sets and exercise variety.
Upper and lower body split
A common next step for intermediates is an upper and lower body split. You train your upper body on two days and your lower body on two days. This gives each muscle group more attention while keeping recovery manageable.
Your week might look like this:
- Monday: Upper body
- Tuesday: Lower body
- Thursday: Upper body
- Friday: Lower body
You keep the same basic rest guidelines as a beginner, 90 to 180 seconds for your main lifts and 60 to 90 seconds for accessory work, but you increase the number of working sets.
Most intermediate lifters use 3 to 5 sets of each main exercise and mix rep ranges. For example, heavier sets of 5 to 8 reps on compound lifts and 10 to 15 reps on smaller isolation moves.
Increasing training volume safely
Because you hit each muscle group twice per week, you have more chances to practice technique and add volume. The key is not to jump from a beginner plan to a huge amount of work all at once. You can:
- Add 1 set per exercise over a few weeks
- Introduce one new accessory exercise per muscle group
- Slightly shorten rest periods on easier exercises to keep intensity up
You should still feel tired at the end of a session, but not destroyed. If your performance suddenly drops or nagging aches appear, you are better off pulling back for a week rather than pushing through and risking a longer setback.
Advanced regimen: High frequency strength training
If you have trained consistently for 2 or more years, and your form and recovery habits are solid, a higher frequency split can help you keep making progress. At this level, the best workout regimen is planned in detail and respects that your body needs more precision to keep adapting.
Six day push pull legs split
Many advanced lifters use a 6 day push pull legs split. You train pushing muscles one day, pulling muscles another, and legs on a third day. Then you repeat that cycle.
Your week could be:
- Monday: Push, chest, shoulders, triceps
- Tuesday: Pull, back and biceps
- Wednesday: Legs
- Thursday: Push
- Friday: Pull
- Saturday: Legs
- Sunday: Rest
You use similar rest times to the other levels, 90 to 180 seconds on big lifts, 60 to 90 seconds on accessories, but you can now play with more advanced methods. Supersets, where you pair two exercises back to back, or higher intensity techniques can increase the challenge without making your workouts much longer.
The trap to avoid is turning every workout into a test. Your goal is steady progression in weight, reps, or movement quality. If you find yourself grinding through every set, you may need a deload week with lighter weights and fewer sets to let your joints and nervous system catch up.
Training smart after 40
Age does not disqualify you from training hard, but it does change your priorities. As you pass 40, your body naturally loses some muscle and bone mass, and joints can feel more sensitive. The best workout regimen for you will respect those realities and keep you strong for the long term.
Joint friendly exercise choices
The main difference is not which muscles you train, but how. You might choose:
- More machine based pressing instead of heavy barbell benching
- Trap bar deadlifts or Romanian deadlifts instead of heavy conventional deadlifts
- Goblet squats, leg presses, or split squats instead of deep back squats
These options still stress your muscles, but often feel kinder to your knees, hips, and shoulders. Starting with a beginner style full body plan is usually smart, even if you used to lift heavier in the past. You can then build back up with careful progression.
Extra time for recovery
You may need longer between hard sessions. That might mean:
- Spacing strength workouts so you never do 3 intense days in a row
- Prioritizing sleep and basic mobility work
- Adding easy days rather than complete off days so you keep moving without more strain
Men over 40 often see better results from slightly lower training volume and slightly higher attention to recovery habits like walking, stretching, and stress management. The goal is sustainable progress, not short bursts of intensity followed by long layoffs due to pain.
How cardio fits into a strength regimen
Strength training is the backbone of the best workout regimen for building muscle and long term fat loss. Muscle mass burns more calories than fat, even when you are resting, so lifting becomes a powerful tool if you want to stay lean.
Cardio still matters. It supports your heart health, helps you burn calories, and can improve your recovery between sets. Many experts suggest adults aim for at least 150 minutes of cardio per week, spread over several days, along with strength training at least twice per week. This blend helps with both fat loss and conditioning.
Choosing the right type of cardio
You have several options to mix with your lifting:
- Steady state cardio such as jogging, cycling, rowing, or using a treadmill
- Higher intensity options such as interval sprints on a rowing machine or incline treadmill walks
- Short High Intensity Interval Training, or HIIT, sessions when time is tight
Time efficient options like HIIT, incline treadmill walks, or rowing sprints help you burn more calories in less time, which is useful if you have a busy schedule. It is important to balance these harder sessions with easier days so you do not show up to your strength workouts already exhausted.
Using the 80/20 rule for endurance and recovery
If you also care about running, cycling, or other endurance sports alongside strength training, the 80/20 method is a proven way to avoid burnout. This approach gives you a simple rule. About 80 percent of your endurance training is at easy intensity and about 20 percent is at hard effort.
This balance is used by many elite athletes and has been effective for endurance athletes of all ages and abilities. Numerous athletes following 80/20 style plans report big improvements in race times and personal bests, including cutting more than 30 minutes from marathon times or close to 40 minutes from half Ironman results, often without injuries or extreme fatigue. Many also credit the approach with preventing burnout and making training feel more sustainable over the long term.
If you enjoy events like half marathons, Ironman 70.3 races, or full Ironman distances, this kind of structure can help you combine strength and endurance without breaking down. Endurance athletes in running, triathlon, cycling, and swimming have used 80/20 programs with coach support and money back guarantees to build fitness, gain speed, and stay consistent. When paired with smart lifting, this balance can keep you strong and fast instead of sore and exhausted.
Why progressive overload and frequency matter
Behind every effective plan is one core idea. Your body grows stronger by handling slightly more stress than before. When you lift weights, you create small tears in your muscle fibers. With enough protein, calories, and rest, those fibers repair and grow back thicker and stronger.
To see this “muscular hypertrophy” over time, you need to:
- Train each muscle group at least two to three times per week
- Do roughly 3 to 4 sets of 8 to 12 reps per exercise for growth
- Gradually increase how hard you work by adding weight, reps, or intensity
Too little challenge and you will not change. Too much and you risk joint pain, lost motivation, or plateaus. Progressive overload lets you walk the line in the middle. You can use free weights for greater muscle engagement and core stability, or resistance machines when you want a safer, guided path, especially as you learn a new movement or target a specific muscle.
Nutrition: Fuel for strength and muscle
Your training plan is only half the story. The best workout regimen for building strength will not deliver if your nutrition works against you. Muscle repair and growth require energy and raw materials, mainly protein.
If your goal is to gain muscle, a slight calorie surplus combined with enough protein is ideal. Many lifters do well with at least 1.4 grams of protein per kilogram of bodyweight from lean meats, dairy, eggs, beans, and other nutritious sources. This intake supports muscle repair after you create those small tears in training.
If you are trying to lose fat while keeping as much muscle as possible, protein becomes even more important. Adequate protein helps you preserve lean mass in a calorie deficit so most of the weight you lose comes from fat instead of muscle. When you combine this with regular strength training and a smart mix of cardio, you protect your strength as the scale moves down.
Think of your regimen as a triangle. Strength work builds and protects your muscle, cardio improves your heart and calorie burn, and nutrition supplies the fuel and building blocks. When all three sides are in place, progress becomes much easier.
Bringing it all together
You do not need a perfect plan to start. You only need a clear, realistic structure that you can follow week after week. For many men, the best workout regimen looks like this:
- Beginners: 3 full body sessions per week with a focus on form and small weekly progress
- Intermediates: 4 day upper and lower split with more sets and variety
- Advanced lifters: 6 day push pull legs rotation with careful use of intensity techniques
- Men over 40: Joint friendly exercise choices, extra recovery, and a beginner style structure to rebuild safely
Layer in 150 minutes of weekly cardio, choose time efficient options like HIIT or incline walking when needed, and protect your nutrition and sleep. Start where you are today. Adjust as you learn how your body responds. When you commit to a structured regimen and respect recovery, strength and confidence follow.
