Look man, bro-splits are king. And I do consider things like upper-body/lower-body to be bro-splits. Anything outside of full-body training in a single session is basically a split. And bro-splits rule for anyone past the rookie stages who wants to maximize development.

But if you can only train 30-minutes a pop, it's best to focus on one, or at most, two muscle groups within that workout. How you decide to finagle it is up to you. First think about how many days you can train, then organize your workouts from there. Here are some templates you can work with based on the number of training days a week you have open:

3 Days A Week

• Day 1: Quads and Hamstrings
• Day 2: Chest and Back
• Day 3: Shoulders and Arms

Ok, so on day 3 you're looking at basically three body parts, but you can knock out some brutal work for biceps in 3 minutes. Don't think so? Try 100 reps of empty-bar barbell curls.

4 Days A Week

• Day 1: Quads
• Day 2: Chest
• Day 3: Back and Hamstrings
• Day 4: Arms

Notice there are hamstrings with back work on day 3. This means the legs are still getting some work twice that week. But you can consolidate back and hamstring work to save time as well, and we'll cover that in a bit.

5 Days A Week

• Day 1: Quads and Hams
• Day 2: Back
• Day 3: Chest
• Day 4: Shoulders
• Day 5: Arms

Notice the sequencing of body parts here? We start with legs, probably your toughest day of the week. Plus, day 1 is often on a Monday, which is International Chest Day. You should have the leg machines and squat rack all to yourself.

The other part of the sequencing is that you may be slightly more fatigued as the week rolls on. You'll be knocking out the two biggest areas in the first two days. From there, you just smash chest, shoulders, and arms. If you set your chest day up properly, you can minimize the work that needs to be done on days 4 and 5.

How? Emphasize progressive overload on chest day. Go for both rep PR's and major strength work on some select compound lifts. Then use the shoulder and arm days as metabolic stress days. Just blast out some ultra high-rep work with single-joint movements. This could also serve as a restorative stimulus from the hard and heavy chest pressing, providing some localized recovery.

Because you're short on time, you'll need to compress your warm-up sets and working sets in a way that maximizes them for each workout.

Warm-up sets are vital for priming the nervous system and the working muscles so that they're efficient on the working sets. When you warm up the working muscles, think of it as "waking up" the nervous system and telling it to activate the target muscles for the movement patterns you're about to perform, i.e. what exercise you're actually doing.

But there's another category of set you need to think about: feeder sets. These are done after your warm-up sets, and they pump some blood into your working muscles. When you do them you'll feel more "in tune" with the movement you're executing.

Feeder sets should be fairly hard, maybe just a couple reps shy of failure. What's the difference between those and working sets? Working sets are the ones that you take to failure, or those where you use intensity methods to further increase the time under tension within the set.

Here's an example of how all that would look:

Warm-Up Sets

• Empty Barbell: 20-40 easy reps
• First Set: Do 15 reps without weight, rest 90 seconds
• Second Set: Add weight, do 12 reps, rest 90 seconds
• Third Set: Add weight, do 10 reps, rest 90 seconds

Feeder and Working Sets

• Fourth set: Add weight (from last warm-up), do 8 reps, rest 120 seconds
• Now begin your working sets, whatever the rep range for them may be.

Here's where effort and time become consolidated. You can either work hard or you can work long, but you really can't do both. At least not consistently. And in the context of this article, you've got 30 minutes.

Here are a couple of set-extending methods that are highly productive for inducing both pain and muscle hypertrophy. (Those often go hand in hand.)

Rest/Pause

Once you've begun your first working set, take it to failure. Then rest for 20 seconds and go back at it. Once you hit failure, rest 20 seconds again and go back for one more round.

You're basically smashing in three working sets in a short timeframe. If you're keeping track in a logbook, or trying to break rep PR's, then try to get more reps in across the board each week than you did before.

For example, if you did dumbbell bench press with the 100's and got 14 reps, 8 reps, and 5 reps respectively (across the rest/pause sets), then that's a total of 27 reps. The next time you ante up for that movement, beat 27.

There are some movements I don't like with rest/pause, like squats and deadlifts. The low back is going to take a beating. Use straight sets for them. With deadlifts, never hit failure for any reason. There's just no need for it since it's too recovery-intrusive.

Drop Sets

Try the 8/8/8 method or the 6/12/20 method. Here's how to do them...

The 8/8/8 drop set is a set of 8 to failure, followed by a decrease in weight using a poundage that allows a successive set of 8, followed by another drop in weight that allows a final set of 8. (Just don't drop the weight so low that you could've done 15 reps each time.)

With the 6/12/20 method, do 6 reps to failure, then a drop to a weight that allows for a set of 12 (performed to failure), then a final drop of 20 reps.

One method isn't really "better" than the other. The best one for you will be the one you use with the most intensity on a consistent basis.

Compound Supersets

Most often, supersets are done using a single-joint exercise combined with a compound/multi-joint movement. With compound supersets you'll be – hold on to your horses – using two compound movements back-to-back.

This isn't unusual when you're pairing antagonist muscle groups, like chest (pushing) and back (pulling). But, believe it or not, there's no rule saying you can't obliterate a muscle using two compound movements back-to-back for it. For example...

• Leg Press and Squat
• Incline Dumbbell Press and Dip
• Chin-Up and Lat Pulldown
• Overhead Press and Upright Row

If you're using one of the splits above where you're hitting one muscle group for the day, then these same-muscle pairings are awesome. But in the 3-days a week split these will work great for super-setting chest and back, quads and hams, and biceps and triceps as well. For example...

• Bench Press and Chin-Up
• Leg Press and Lunge (a glute destroyer)
• Tricep Dip and Supinated Grip Chin-Up

Giant Sets/Circuit Work

Do a whole slew of exercises in a row with no rest until all movements are completed. I like these more using single-joint movements rather than smashing in a bunch of compound movements. You can create a really bad-ass metabolic stress session for certain muscle groups without impacting your recovery on the bigger lifts.

Pre-Exhaustion

Use a single-joint exercise for a muscle group before moving on to a multi-joint exercise for that same muscle group. The idea behind it is that all compound movements have a "weak link" in the musculature that keeps the primary muscle you're trying to work from getting blasted as hard as it could.

For example, with squats the low back will take a fairly solid beating while the quads could actually handle more work. When you use pre-exhaustion you level the playing field by starting with leg extensions then immediately moving to a set of squats. Theoretically, the quads are now fatigued and the low back isn't the "weak link" in the kinetic chain.

Other examples would be flyes before bench or incline press, lateral raises before overhead pressing, and pullovers before chins or rows. This is a great method to really smash the living hell out of a body part in short order.

Be cognizant of overlap – you want it. When you bench press, you're working the chest, shoulders, and triceps. When you do dips, same thing. However, you can emphasize more triceps with a close-grip bench press, or you can emphasize more of the pecs with dips with a big forward lean at the bottom.

Both are compound movements that basically work the same muscle groups. But the execution of them will dictate which area is going to get a little more work.

By "overlap" I mean you can hit all of these areas multiple times a week if you're one of those guys that freaks out that you're not hitting chest enough during the week. You don't really need to sweat it if you're smashing chest one day with bench press, then triceps a few days later with dips. It really means you're smashing chest, shoulders, and triceps at least twice that week.

I'm giving the busy gym bro a lot to work with here. There's literally a million ways all of this could be cooked up to create some productive training splits. Here are some examples:

Day 1 – Quads and Hams

• Compound Superset: Do hack squats and lunges. After warming up, do 3 rounds of 20 hacks, supersetted with 20 lunges.
• Leg Curl: Do the 8/8/8 or 6/12/20 drop set.

Day 2 – Chest and Back

• Compound Superset: Do dumbbell bench press and chins or rows (alternate these week to week). After warming up, do 5 rounds of 8 reps on dumbbell bench and as many reps as possible for chins. If it's a row week, do 5 x 8 for rows.

Day 3 – Shoulders and Arms

• Circuit or Giant Sets: Do 25 reps per lift, take no rest between them, and repeat this circuit 4 times with 2 minutes rest between each.

• Lateral Raise
• Bentover Lateral Raise
• Tricep Pushdown
• Barbell Curl

Day 1 – Quads

• Pre-Exhaustion: Use leg extensions and heel-elevated squats. Do 3 rounds of 15 reps for leg extensions and 10 reps each round for squats.

Day 2 – Chest

• Compound Superset: Incline dumbbell press and dips. Do 4 rounds of 8 reps for the dumbbell press and as many reps as possible for the dips.
• Flat Flye: Do the 8/8/8 or 6/12/20 drop set.

Day 3 – Back and Hamstrings

• Compound Superset: Deficit stiff-leg deadlifts and chins. Do 3 sets of 6 reps for the deadlifts and 3 sets of as many reps as possible for the chins.
• Leg Curl: Do the 8/8/8 or 6/12/20 drop set.

Day 4 – Arms

• Circuit or Giant Sets: Do 25 reps per lift, take no rest between them, and repeat this circuit 4 times with 2 minutes rest between each.

• Barbell Curl
• Pushdown

• Overhead Rope Extension

Day 1 – Glutes, Quads and Hams

• Drop Set Pre-Exhaustion: Start with leg extensions, do the 6/12/20 or 8/8/8 drop set immediately followed by hack squats for one all-out set of 20 reps.
• Compound Superset: Do the sumo leg press and dumbbell Romanian deadlifts for 3 rounds of 10 reps on the leg press and 8 reps for RDL's.

Day 2 – Back

• Giant Set (with pre-exhaustion): Don't rest between lifts, repeat this circuit 4 times, and take 3 minutes rest between each round:

• Dumbbell Pullover: 10 reps
• Chin-Up: As many reps as possible
• Low Cable Row: 10 reps

Day 3 – Chest

• Incline Press: Do the 8/8/8 or the 6/12/20 drop set.
• Pre-Exhaustion Superset: Do flat flyes or pec deck and bench press or Hammer Strength chest press. Do 3 rounds of 12 reps for flyes and 8-10 reps for the bench or the chest press.

Day 4 – Shoulders

• Pre-Exhaustion Superset: Do lateral raises and overhead presses (any variation) for 3 rounds of 12 reps on lateral raises and 8 reps on overhead presses.
• Superset: Do facepulls with bentover lateral raises, 3 rounds of 12 reps for each.

Day 5 – Arms

• Biceps Giant Set: Do 4 rounds of 12 reps on EZ-bar preacher curls, standing preacher curls, and incline dumbbell curls.
• Triceps Giant Set: Do 4 rounds of 12 reps on rope pushdowns, overhead rope extensions, and bench dips.

Rather than focus on a particular routine, focus on the principles here and become your own case study. Use this as a loose guide to figure out what fits into your limited training window, and what training strategies you like best.

It could be as simple as just showing up and doing some straight sets to failure with one or two movements. And if you enjoy that and are consistent with it, you'll see progress.

Remember, you don't need permission to try something new. Be your own researcher here. Plan for exercises and intensity techniques for that 30-minute window and then flesh out the things you enjoy. Discard what doesn't work for you.
