If your goal is to maximize your workout time and see real results, you’ve likely wrestled with this question before. Should cardio come before weights, or is it more effective to lift first and save cardio for last? Believe it or not, the sequence of your workout can significantly impact your fitness outcomes.

Certainly the answer isn’t one-size-fits-all. It depends on your unique fitness goals, whether that’s building muscle, losing weight, or increasing endurance. So, to help you decide, we’ll break down the pros and cons of each approach, share expert opinions, and give you actionable advice you can use to fine-tune your workouts.

Understanding Your Fitness Goals

When deciding whether to start with cardio or weights, understanding your goals is the critical first step. Indeed the decision might vary depending on what you’re aiming to achieve.

Weight Loss

If your primary goal is to lose weight, the sequence may not matter as much. Weight loss generally comes down to burning more calories than you consume. So even if you just strength train, you can possibly still lose weight. However, both cardio and weights play different roles in that calorie burn. Strength training builds lean muscle, which increases your resting metabolic rate, while cardio burns calories during the exercise itself. Hence a balanced approach of both can give you the best of both worlds.

Muscle Building

If packing on muscle is your mission, of course weights should come first. Lifting requires peak energy and focus, so entering the weight room after a tiring cardio session could compromise your performance. For example, studies suggest that starting with strength training enables heavier lifts (higher volume=more muscle growth), better technique, and greater muscle hypertrophy (growth).

Endurance

So for those training for endurance-based activities like running marathons or cycling events, cardio should take priority. Firstly, starting with cardio ensures your energy goes toward improving your cardiovascular foundation, which is essential for this type of training. Lastly, for this type of goal strength training and cardio is ideal on a separate days.

Cardio Before Weights: The Pros and Cons

Pros

• Boosted Cardiovascular Endurance

Firstly starting with cardio preps your heart and lungs for intense physical exertion, making this approach ideal for improving stamina.

• Natural Warm-Up

Cardio before weights elevates your heart rate and loosens up your muscles, reducing the risk of injury during strength training.

Cons

• Potential Fatigue

High-intensity cardio can leave you drained, therefore resulting in a less effective weightlifting session.

• Compromised Strength Performance

For instance, studies show that lifting after cardio may reduce the weights you’re able to handle, affecting your muscle-building potential.

Weights Before Cardio: The Pros and Cons

Pros

• Enhanced Muscle Growth

Thus lifting first allows you to tackle heavier weights with proper form, leading to better gains in strength and muscle mass.

• Improved Fat Burning

Post-lifting cardio taps into stored fat reserves due to depleted glycogen (carbohydrate energy), making it an effective weight-loss strategy.

Cons

• Glycogen Depletion for Cardio

Strength training can use up glycogen, your body’s primary energy source, which may limit your performance during cardio.

• Not Fully Warmed Up

Certainly, jumping straight into weights without a proper warm-up could increase the chance of injury.

Expert Opinions

Fitness experts and researchers generally agree on one principle when it comes to workout order: prioritize what aligns with your main goal, and do it first.

So if building muscle is your goal, weights should come first. For endurance or cardiovascular health, start with cardio instead.

In fact, the American Council on Exercise (ACE) echoes this by recommending individuals tailor workout structure to their goals. ACE research also highlights that different types of cardio (e.g., running vs. cycling) can have varying impacts on weight training.

For a balanced progression, experts recommend alternating workout sequences occasionally or adopting a periodization strategy (phases of high-intensity cardio followed by strength).

Practical Recommendations

Also here’s how to organize your sessions based on your fitness level and goals.

For Beginners

Start with a balanced workout that incorporates both cardio and weights. Therefore, this approach helps establish a solid fitness foundation and familiarises you with different types of exercises. For example:

• Warm-up: 5 minutes of light cardio
• Strength Training: Full-body circuit (30 minutes, using moderate weights)
• Cardio: Lastly 15–20 minutes of steady-state or low-intensity intervals

For Intermediate/Advanced Individuals

Tailor your workout order to your primary goal.

• Muscle building? Firstly begin with weights using heavier loads, and finish with light walking cardio.
• Endurance focus? For example hit the treadmill, track, or bike first, followed by strength exercises like bodyweight moves or do them on a separate day.

To Avoid Plateaus

So… switch up your routines! However, periodically alternate your workout strategy, to challenge your muscles and cardiovascular system in new ways.

Sample Workout Routines

Cardio-Focused Routine

Goal: Build endurance while maintaining strength

• Warm-up: 5–10 minutes of dynamic stretches
• Cardio: 20–30 minutes of high-intensity intervals (e.g., sprints or cycling)
• Weights: Full-body circuit with higher reps and lower weight

Strength-Focused Routine

Goal: Maximize muscle growth

• Warm-up: Dynamic stretching or 5 minutes of easy rowing
• Weights: 40 minutes of compound lifts (e.g., deadlifts, squats, bench press) paired with accessory moves
• Cardio: 10–15 minutes of moderate intensity (cycling or treadmill)

Hybrid Routine

Goal: General fitness and calorie burning

• Warm-up: Firstly, 3 minutes of jogging + 2 minutes jogging
• Circuit Training (30 minutes): Alternate strength and cardio moves (e.g., Deadlifts and Kettlebell swings or some plyometric jumps)
• Cool Down with stretching

Finding What Works for You

In conclusion, the “right” workout order depends on your goals, preferences, and how your body responds.

Consistency is key. So stick to a plan for 6-8 weeks to see what works for you. Whether you’re in weight loss or a cardio-hesitant lifter, mixing cardio and strength training can be a powerful combination when done correctly.
