Should You Avoid Cardio When Trying to Gain Weight?

Should you avoid cardio when trying to gain weight

When working to grow your glutes and legs, it’s natural to question whether cardio is helping or hurting your progress.

For women lifting heavy and trying to gain weight, there’s one common concern: Will cardio kill my gains?

Let’s break it down.

Cardio Isn’t the Enemy, But Context Matters

Cardio often gets a bad rep in muscle-building circles. But here’s the truth: cardio isn’t the problem… misused cardio is.

If your goal is to build muscle and gain weight, especially in your glutes and legs, cardio needs to be approached strategically.

Why You Shouldn’t Completely Cut Out Cardio:

1. Cardio Supports Recovery

Low-intensity cardio (like walking or cycling) helps increase blood flow, which can support recovery between heavy leg days.

2. Cardio Keeps Your Heart Healthy

Just because you’re bulking doesn’t mean your cardiovascular system should be ignored. Even short sessions of cardio support overall health and endurance.

3. Better Work Capacity in the Gym

A healthy cardio base improves your work capacity, letting you handle more sets, reps, and intensity during your lifts — key for growing glutes and legs.

When Cardio Can Interfere With Gains

If you’re doing too much cardio – especially high-intensity or long-duration – it might be working against your muscle-building goals.

  • Too Much Calorie Burn: You need to be in a caloric surplus to build muscle. Excessive cardio may burn too many calories, making it harder to gain weight.
  • Recovery Drain: Too much cardio can leave you fatigued and impact your ability to recover from heavy lower-body sessions.
  • Mixed Signals: Lifting tells your body to build muscle. Long cardio sessions can send the opposite signal, potentially blunting growth.

The Best Cardio Strategy for Women Lifting Heavy

If you’re working hard to grow your glutes and legs, use cardio in a way that complements (not competes with) your goals.

1. Stick to Low-Intensity

Opt for steady-state cardio like incline walking, light cycling, or swimming. Aim for 20–30 minutes, 1–3 times per week.

2. Schedule Smartly

Do cardio on rest days or upper body days, not on heavy leg training days.

3. Fuel Like You Mean It

Make sure you’re eating enough calories and protein to support muscle growth. If you include cardio, slightly increase your intake to stay in a surplus.

4. Watch How You Feel

Feeling overly sore, tired, or plateauing? It might be time to cut back on cardio and let your muscles recover.

Final Thoughts: Should You Ditch Cardio Completely?

No, you don’t need to avoid cardio altogether.

But if you’re trying to gain weight and build strong, sculpted glutes and legs, cardio should be minimal, strategic, and supportive of your training.

Summary – Cardio & Muscle Building for Women

  • Cardio is fine in moderation
  • Choose low-intensity options
  • Schedule cardio away from leg day
  • Make sure you’re eating enough
  • Prioritize progressive overload and recovery
