Concurrent Training: How to Combine Lifting and Cardio
A practical guide to concurrent training: how to structure your weekly program to include both strength training and cardiovascular exercise without compromising either.
# Concurrent Training: How to Combine Lifting and Cardio
Most people need both strength and cardiovascular fitness. Concurrent training is the practice of training both within the same program. While the interference effect (covered in our article on whether cardio kills gains) is real, intelligent programming largely neutralizes it. Here is how to structure a program that develops both qualities effectively.
The Principles of Concurrent Training
Principle 1: Prioritize According to Your Goals
Whatever matters most to you should get the best of your energy, time, and recovery resources. If strength and muscle are your primary goals, lifting sessions should come first in the day and receive more weekly volume. Cardio supports the program but does not dominate it. If cardiovascular fitness or endurance performance is your priority, flip the emphasis.
For most lifters reading this, strength is the priority. The programming examples below reflect that assumption.
Principle 2: Separate Stimuli When Possible
The interference effect is minimized when strength and cardiovascular sessions are separated by time. Ideally, put 6 to 24 hours between a cardio session and a lifting session. This allows the molecular signaling from each type of training to operate without competing for the same adaptive resources.
If separation is not possible, perform strength training first and cardio second. Studies consistently show that this order produces better strength outcomes than the reverse.
Principle 3: Match Cardio Modality to Your Goals
Low-impact, concentric-dominant cardio (cycling, rowing, swimming, elliptical) produces less interference with strength training than high-impact modalities like running. If your primary goal is to build strength and muscle while improving cardiovascular fitness, choose modalities that spare your joints and muscles for lifting.
Walking is the exception to all rules. It is so low in stress that it can be done daily in virtually unlimited amounts without meaningful interference. Think of walking as a baseline activity, not a training session.
Principle 4: Manage Total Training Stress
Your body does not separate "lifting stress" from "cardio stress." It experiences total stress. Adding three HIIT sessions to an already demanding four-day lifting program may push you past your recovery capacity, even if each individual session seems manageable.
Monitor symptoms of accumulated fatigue: declining performance in the gym, elevated resting heart rate, persistent soreness, poor sleep quality, low motivation, and increased irritability. If these appear, reduce training volume before reducing intensity.
Principle 5: Fuel the Work
Concurrent training burns more calories than either modality alone. Under-eating while training both strength and cardio is a recipe for stalled progress, muscle loss, and eventual burnout. Eat enough to support both types of training, with particular attention to protein (1.6 to 2.2 g/kg/day) and carbohydrate intake (sufficient to replenish glycogen for both lifting and cardio).
Sample Weekly Templates
Template 1: Four-Day Lift, Minimal Cardio (Strength Priority)
This template is for lifters who want to add cardiovascular health benefits with minimal compromise to their strength program.
- Monday: Upper body strength
- Tuesday: Lower body strength + 20 min Zone 2 cycling (post-lift)
- Wednesday: 30-45 min Zone 2 walk or easy cycle
- Thursday: Upper body strength
- Friday: Lower body strength
- Saturday: 30-45 min Zone 2 cardio (any modality) + optional HIIT (20 min cycling intervals)
- Sunday: Rest or light walking
Template 2: Four-Day Lift, Moderate Cardio (Balanced Approach)
For lifters who want meaningful cardiovascular improvement alongside their strength work.
- Monday: Upper body strength (AM), 30 min Zone 2 cycling (PM)
- Tuesday: Lower body strength
- Wednesday: 40-60 min Zone 2 cardio + 20 min HIIT intervals
- Thursday: Upper body strength (AM), 30 min Zone 2 walk (PM)
- Friday: Lower body strength
- Saturday: 45-60 min Zone 2 cardio (long session)
- Sunday: Rest or light walking
Template 3: Three-Day Lift, Higher Cardio (Cardiovascular Priority)
For lifters who want to maintain strength while making cardiovascular fitness the focus.
- Monday: Full body strength
- Tuesday: 45-60 min Zone 2 cardio (AM), 20 min HIIT (PM or as second part of session)
- Wednesday: Full body strength
- Thursday: 45-60 min Zone 2 cardio
- Friday: Full body strength
- Saturday: 60-90 min Zone 2 long session
- Sunday: 30 min easy recovery cardio or rest
Template 4: The Daily Mover (General Health Focus)
For people who want overall health and fitness without strict optimization of either quality.
- Monday: Upper body strength + 20 min Zone 2 post-lift
- Tuesday: 30-40 min Zone 2 cardio
- Wednesday: Lower body strength + 20 min Zone 2 post-lift
- Thursday: 30-40 min Zone 2 cardio + 10-15 min HIIT finisher
- Friday: Full body strength
- Saturday: 45-60 min recreational activity (hike, bike ride, swim)
- Sunday: Active recovery walk, 30-60 min
Exercise Selection for Concurrent Training
Best Cardio Choices for Lifters
Incline treadmill walking: Zone 2 heart rates with zero impact. Set the treadmill to 10 to 15 percent incline and walk at 3.0 to 3.5 mph. This is surprisingly demanding cardiovascularly while being extremely joint-friendly.
Stationary cycling: Easy to control intensity, zero impact, and primarily targets muscles that recover relatively quickly (quads, as opposed to the hamstrings and glutes heavily loaded during deadlifts and squats).
Rowing ergometer: Full-body modality that can serve as Zone 2 work or intervals. The hip hinge pattern has some carryover to lifting movement patterns. Keep the stroke rate low (18 to 22 per minute) for Zone 2.
Assault/air bike: Excellent for HIIT. The full-body nature distributes the workload and avoids overloading any single muscle group.
Cardio to Approach with Caution
Running: High eccentric loading, particularly problematic for lower body recovery. If you run, keep volume moderate and avoid it the day before heavy lower body sessions.
Stair climbing: Can be excellent for Zone 2, but can also accumulate significant quadricep fatigue. Use sparingly around leg days.
Sport-specific activities: Recreational sports (basketball, soccer, tennis) are great for enjoyment but unpredictable in intensity and carry injury risk. Account for them in your recovery budget.
Periodization Strategies
Block Periodization
Alternate emphasis between strength and cardiovascular blocks. Spend 4 to 6 weeks with higher lifting volume and minimal cardio, then 4 to 6 weeks with reduced lifting volume and increased cardio. This approach minimizes concurrent interference by reducing the degree of simultaneous stimulus.
Undulating Approach
Vary the emphasis within each week rather than across blocks. Two to three heavy lifting days combined with two to three cardio days, with intensity and volume waving across the week. This is the most common approach and works well for general fitness.
Seasonal Approach
Many lifters naturally shift emphasis with seasons. Heavier lifting focus in fall and winter, more outdoor cardio and lighter lifting in spring and summer. This provides variety and matches natural activity patterns.
Monitoring and Adjusting
Track key metrics to ensure your concurrent program is working:
- Strength progression: Are your lifts continuing to improve, even if slowly?
- Resting heart rate: Is it stable or gradually decreasing? An upward trend suggests accumulated fatigue.
- Body composition: Is your body composition moving in the desired direction?
- Energy and mood: Do you feel generally good, or chronically fatigued?
- Sleep quality: Is sleep remaining restorative?
The Key Takeaway
Concurrent training is not just possible; it is the ideal approach for most people who want to be healthy, capable, and resilient. The interference effect is manageable with intelligent programming, appropriate exercise selection, adequate nutrition, and honest self-monitoring. You do not have to choose between being strong and being fit. With the right approach, you can be both.
