Lifting and Cardio on the Same Day: Which First?

Most people with a job cannot give lifting and cardio separate days every time. So you train both on the same day, and the question follows: which one goes first? The answer depends on your goal, the type of cardio and how much time you leave between the two.

Here is the short version. If strength or muscle is your priority, lift first. If you can, leave several hours between sessions. Keep same-day cardio easy unless the day is built around it.

Lift first if strength is your goal

Order matters most for lower-body strength. A meta-analysis by Murlasits and colleagues compared strength-first with endurance-first sessions. Lower-body 1RM rose about 3.96 kg more when strength came first, and order had no effect on VO2max.

"Sequencing strength training prior to endurance in concurrent training appears to be beneficial for lower body strength adaptations, while the improvement of aerobic capacity is not affected by training order."

Murlasits Z, Kneffel Z, Thalib L. The physiological effects of concurrent strength and endurance training sequence. Journal of Sports Sciences, 2018.

A second review agrees. Eddens, van Someren and Howatson pooled 10 studies and found a 6.91% greater gain in lower-body dynamic strength with resistance work first. Order made no difference to muscle size, aerobic capacity or body fat.

That gives you a simple rule. Your aerobic fitness improves either way, so you lose nothing by putting the barbell first.

When cardio can go first

Lifting first is the default, not a law. Put cardio first in these cases:

• The cardio is the key session of the week, such as a race-pace interval workout before an event.
• The lift is upper body only. Running before a bench and row session costs your pressing very little.
• The cardio is a short, easy warm-up. Five to ten minutes on a bike or rower prepares you to lift.

When cardio goes first, keep the lifting focused. Do your main lift and one or two accessories, then finish.

How much time to leave between sessions

Spacing helps more than order. A 2022 Sports Medicine meta-analysis of 43 studies found that adding aerobic work did not reduce gains in muscle size or maximal strength. Explosive strength did suffer when both modes shared one session, but not when sessions were at least 3 hours apart.

Use these spacing targets:

• Best: lifting and hard cardio on different days.
• Good: an AM and PM split with 6 or more hours between them, plus a meal.
• Workable: at least 3 hours apart.
• Same session: lift first, then easy cardio.

Trained lifters have the most to gain from spacing. A meta-analysis by Petré and colleagues found that the squat and leg press loss in trained people appeared only when both modes shared a session.

Match the cardio type to the lifting day

Not all cardio stresses your legs the same way. Pair them with intent.

Keep most same-day cardio easy. Seiler's review of endurance training distribution found that successful endurance athletes do about 80% of sessions at low intensity and about 20% as hard intervals. Easy sessions are the ones that stack well with lifting.

Heavy lower day

Do the lift first, with full rest. Follow it with 15 to 25 minutes of easy cycling or rowing, or save the cardio for the next day. Avoid hard running intervals within a few hours after a heavy squat session.

Upper body day

This is the easiest day to stack. Lift, then do intervals or a tempo run. Or run in the morning and lift in the evening.

Interval day

Treat intervals as a lower-body session in their own right. A meta-analysis of HIIT and lifting by Sabag and colleagues found that concurrent HIIT slightly reduced lower-body strength gains. The authors suggested running-based intervals and longer rest between modes to limit that effect.

Sample same-day sessions

Each template takes 60 to 75 minutes when combined, or two shorter blocks when split.

Strength priority, lower body

1. Warm-up: 5 minutes easy bike, then empty bar sets
2. Back squat: 4 x 4 at 80-85% of 1RM, 3 minutes rest
3. Romanian deadlift: 3 x 6 at RPE 7
4. Hamstring curl: 2 x 12
5. Easy bike or row: 20 minutes, conversational pace

Strength priority, upper body plus intervals

1. Bench press: 4 x 5 at 78-83% of 1RM
2. Weighted pull-up: 4 x 5
3. Dumbbell row: 3 x 10
4. Intervals: 6 x 2 minutes hard, 2 minutes easy on the rower or treadmill

Endurance priority, AM and PM split

• AM: tempo run, 10 minute warm-up, 20 minutes at a comfortably hard pace, 10 minute cool-down
• PM, 6+ hours later: front squat 3 x 5 at RPE 7, push-up 3 x 15, chin-up 3 x 8, plank 3 x 45 seconds

Fuel and recover between sessions

A same-day double needs food in the gap. Eat a meal with carbohydrate and protein after the first session. Drink water and keep the second session's warm-up thorough.

Sleep holds the whole week together. If you only get one quality block in a day, make it the one that matches your current priority.

Put these rules into a plan you can follow. Open the free program builder and enter your training days, your main lift 1RMs and which days hold both lifting and cardio. Set your priority to strength or endurance, and order each day to match.
