5x5 and Powerlifting Strength Routines: guide and 5 routines

What a strength routine is

A strength routine aims to get you lifting more weight in a few exercises, mainly the back squat, the bench press, the deadlift and the barbell shoulder press. To do that, it works those main lifts with heavy loads, from 2 to 8 reps per set depending on the routine, and with long rests between sets. The rest of the session is accessories with more reps, which add muscle and work the areas the main lifts don't cover.

The difference from a muscle building routine is the load. Muscle grows similarly with light or heavy loads if the sets are hard, but maximal strength goes up more with heavy loads (Schoenfeld et al., 2017). In a network meta-analysis, prescriptions above 80% of 1RM gave the most strength, and all of them promoted similar muscle growth (Currier et al., 2023). The ACSM (2026) also includes loads of 80% of 1RM or more among the things that improve strength.

That advantage shows up mostly when you test your max in the same kind of exercise you trained. In isometric strength there were no differences between high and low loads (Schoenfeld et al., 2017). That's why these routines repeat the same main lifts week after week: to lift more in the squat you have to practice heavy squats. At first, a good part of what improves is nervous system adaptation more than muscle size (ACSM, 2009). Moderate loads also raise strength, just less (Currier et al., 2023).

How the main lifts are spread across the week

Strength routines repeat each main lift more than once a week. Strength 5x5 3 Days squats all three days and alternates the bench press with the shoulder press. Powerlifting Strength 4 Days squats and benches twice and deadlifts once. Max strength 4 days takes the squat and the bench, with their variations, to three times a week.

Three ways to split a strength week
Day	5x5	Powerlifting	Max strength
Monday	Day A	Squat	Squat
Tuesday	Rest	Bench	Bench
Wednesday	Day B	Rest	Rest
Thursday	Rest	Deadlift	Deadlift
Friday	Day C	Technique	Volume
Saturday	Rest	Rest	Rest
Sunday	Rest	Rest	Rest

The ACSM (2026) found that strength improves when training at least 2 sessions a week, and couldn't set a maximum. Grgic et al. (2018) saw more strength with higher frequency, but when volume was matched the difference disappeared, so frequency mostly serves to spread more work out. Pelland et al. (2026) do see strength rise with frequency, although each extra session adds less. In practice, repeating a main lift 2 or 3 times a week lets you do more quality heavy sets without endless sessions.

In the 4-day versions, the deadlift comes after a rest day and the fourth day lowers the demand. In Powerlifting it's a technique day, with squats at RIR 3 and accessories. In Max strength it's a volume day with variations, like the front squat and the dumbbell incline bench press.

Which strength routine to choose

You're starting with the main lifts. Strength 5x5 3 Days has three exercises a day and fits in an hour. Start light: the ACSM (2009) suggests moderate loads, 50 to 60% of 1RM or less, while you learn the technique. If it's your first routine, there are also the beginner routines.
You want strength and muscle at once. Intermediate Full Body 3 Days puts a different heavy main lift on each day and rounds out with accessories. Strength and hypertrophy hybrid 4 days alternates a heavy day and a volume day for upper and lower body.
You're interested in the three powerlifting lifts. Powerlifting Strength 4 Days revolves around the squat, bench and deadlift, with accessories that don't overload the lower back.
You've been training for years and want a strength peak. Max strength 4 days is an 8-week block with loads that rise in a planned way and ends with a deload or test week.

The number of days goes with your level. The ACSM (2009) proposes 2 to 3 days a week for beginners, 3 to 4 for intermediate and 4 to 5 for advanced. If your main goal is to build muscle and not to lift more, you grow similarly with moderate loads, and the muscle building routines give you more volume per muscle.

Sets, rest and effort

Strength takes fewer sets than muscle. The ACSM (2026) sees strength gains flatten after about 2 to 3 sets per exercise, and advises doing at least two. Pelland et al. (2026), with 67 studies, find that strength goes up with volume, but with much sharper diminishing returns than muscle. That's why the main lifts go with 3 to 5 heavy sets and the rest of the volume comes from accessories.

Direct sets per week in three Mobbe strength routines
Muscle	Strength 5x5 3 Days	Powerlifting Strength 4 Days	Max strength 4 days
Chest	10 over 2 days	11 over 2 days	11 over 3 days
Back	6 over 2 days	6 over 2 days	9 over 3 days
Shoulders	5 over 1 day	3 over 1 day	3 over 1 day
Quads	15 over 3 days	11 over 2 days	11 over 3 days
Hamstrings	1 over 1 day	10 over 2 days	9 over 2 days

The table counts the sets where each muscle is the primary one and the days it's trained. The deadlift counts for hamstrings, although it also works glutes and lower back, and the squat adds to the glutes. In the 5x5, the squat on all three days already loads the hips, and the deadlift goes in a single heavy set of 5.

Rest more than you would in a muscle routine. In trained people, more than 2 minutes between sets works better for strength (Grgic et al., 2018), and the ACSM (2009) proposes 3 to 5 minutes for heavy work. Mobbe routines give 3 to 4 minutes on the main lifts and 1 to 2.5 minutes on accessories. If you're just starting, 60 to 120 seconds is enough to gain strength (Grgic et al., 2018).

You don't need to reach failure. A meta-analysis found no strength differences between training to failure and not (Grgic et al., 2022), and in one study failure delayed recovery by 24 to 48 hours (Morán-Navarro et al., 2017). Mobbe's strength routines leave 2 or 3 reps in reserve (RIR) on the main lifts, as the ACSM (2026) proposes.

Common mistakes when training strength

Testing your max every week. A 1RM is a test, not a workout. The 1RM calculator estimates it from a set of several reps. Save the real test for the end of a block, like week 8 of Max strength 4 days.
Going straight to the working load. Before the heavy sets, do several warm-up sets, first with the empty bar and then with rising loads, with few reps so you don't get tired.
Shortening the range of motion to lift more weight. The ACSM (2026) includes full range of motion among the things that improve strength. Always squatting to the same depth and touching your chest on the bench is also the only way to compare one session with another.
Training heavy without protection. On the squat and bench press, set the rack safety bars a little below the lowest point of the movement, or ask someone to spot you. If a rep comes out much slower than the previous ones, end the set there.

How to progress in strength

Strength is built by raising the load little by little. The ACSM (2009) proposes going up 2 to 10% when you do 1 or 2 more reps than targeted in two sessions in a row, with smaller increases on small-muscle exercises. Mobbe's strength routines apply that idea in three ways.

Fixed increase: Strength 5x5 3 Days, Powerlifting Strength 4 Days and Strength and hypertrophy hybrid 4 days add 2.5 kg on the main lifts when you complete all sets at the indicated RIR. If you fail two sessions in a row, you drop 10% and build up again.
Double progression: Intermediate Full Body 3 Days adds reps within the range and raises the smallest available increase when all sets reach the top.
Planned block: Max strength 4 days does weeks 1 and 2 at RIR 2 or 3, raises the load by 2.5 to 5% per week from 3 to 6, does 3 heavy sets of 2 or 3 reps in week 7 and leaves week 8 to deload or test your max. For the advanced level, the ACSM (2009) recommends precisely varying volume and intensity systematically.

To choose your starting weight, the 1RM calculator estimates your max and the weights for each percentage. Starting a bit lighter than you could gives you several weeks of increases before the first plateau. RIR also helps adjust the load: the ACSM (2026) points out that effort scales let you raise the weight as you get stronger, keeping the same relative load.

It's normal for the pace to slow over time, because you can't keep improving at the same rate (ACSM, 2009). If the load stalls for several sessions in a row, check your sleep and food before touching the routine, and the calorie calculator gives you a starting point. If it stays the same, do a week with about half the sets. The consensus from Bell et al. (2023) agrees that a deload lowers the volume and that the load can be kept only if the volume drops. It also finds no evidence that you need to schedule one every set number of weeks.

In Mobbe every set is saved. When you train you see what you lifted last session on each exercise, and in Progress you see your records go up.

Questions about strength routines

How much rest between heavy sets?

On the main lifts, 3 to 5 minutes, as the ACSM (2009) proposes. In trained people, more than 2 minutes works better for strength (Grgic et al., 2018). You also gain strength with short rests, but less if you've been training for a while.

Do I have to test my 1RM to use percentages?

No. The [1RM calculator](/calculadoras/1rm) estimates it from a set of several reps, and the RIR of each set tells you whether the load is right. If you want to test your max, do it rarely, with a good warm-up and safety bars.

Do I build muscle with a strength routine?

Yes. Muscle grows similarly with high or moderate loads if the sets are hard (Schoenfeld et al., 2017). What changes is the volume: muscle grows more with more sets (Pelland et al., 2026), so if you want both, a hybrid routine suits you better.

In what order do the exercises go?

The main lift of the day goes first. Strength goes up more on the exercises you do at the start of the session (Nunes et al., 2021), so accessories go after, once you've finished the heavy work.

Can I do cardio with a strength routine?

Yes. In a meta-analysis of 43 studies, adding aerobic exercise didn't hold back muscle or maximal strength (Schumann et al., 2022). If you do them on the same day, lifting first was linked to more leg strength (Murlasits et al., 2018).
