Supersize Your Chest With This Four-Week Plan

Broad shoulders, a barn-door back or a sleeve-stretching set of arms are all noble goals to strive towards, but let’s face it, there’s a reason that ‘international chest day’ is consecrated at the beginning of the week and not the end — for a lot of men, a hulking set of pecs is a high priority.

This four-week, research-backed, high-volume, chest-specialisation programme is custom designed to pump up your pecs, adding slabs of lean muscle to your chest in no time flat.

Training four days per week, you’ll be utilising ‘the priority principle’ and beginning each session with laser focussed attention to building the strength, thickness and size of your chest, before moving on to other muscle groups for balance and maintenance.

Each day emphasises a different area of your chest or a different quality – moving from heavyweight lifts to high-rep burners to ensure complete pectoral perfection. Spreading the work across the week in this fashion, prioritising the chest at the beginning of each session, ensures that you can pour maximum effort into each chest movement.

Repeat sessions A, B, C and D each week for four weeks. Take notes and follow the progression tips to ensure you’re making headway. Try to rest for 24-48 hours between each session, or perform a low-intensity cardio workout or mobility on your rest days.

To fuel your pec popping gains, ensure you’re taking on adequate calories and consuming enough protein, aiming for around 2g of the good stuff per kilogram of bodyweight.

Session A

1. Dumbbell Bench Press- 5 sets of 5 reps

Lay flat on a bench, your knees bent, pushing your feet into the floors. Press a pair of dumbbells into the air, locking out your elbows (A). Lower the bells slowly until they touch your chest (B) keep your elbows at a 45-degree angle, pause here before explosively pressing back up. Repeat. Rest two minutes between sets

Perform a few warm-up sets and then choose a weight that allows you to have 2-3 reps in reserve for the first set, but is a struggle to hit 5 reps with on the last few sets. If you manage all 25 reps with good form, go heavier next week.

2. Dips – 5 sets of 10 to 15 reps

Jump up on two parallel bars with your palms facing inward and your arms straight (A). Use two boxes or the backs of two sturdy chairs if you’re at home. Slowly lower until your elbows are at right angles, ensuring they don’t flare outward (B). Drive yourself back up to the top and repeat. Rest 90 seconds between sets.

Add weight if you can, but attempt to stay between 10-15 reps. If you manage more than 50 total reps, go heavier next week.

3. Chin-ups (or Lat Pulldown) – 4 sets of 6 to 12 reps

Grab a pull-up bar with your palms facing your body. Lift your feet off the floor and hang freely with straight arms (A). Pull yourself up by flexing your elbows and pinching your shoulders together. When your chin passes the bar, pause (B), before lowering to the starting position. Try not to swing too much. Rest two minutes between sets. If this rep range is too difficult to maintain, use a band for assistance or the lat pulldown machine.

4. Chest Support Dumbbell Row – 4 sets of 10 to 15 reps

Set an adjustable bench to around 45 degrees or prop a flat bench up with a box. Position yourself face down with your chest on the pad, holding a pair of dumbbells (A). Staying tight to the bench, row both dumbbells up towards your hips, pause (B) and slowly lower before repeating. Rest 90 seconds between sets. Choose challenging weights.

5. Barbell Curl x 100 (total)

Stand tall with an empty olympic (or light) barbell, with your palms facing towards you, shoulder-width apart (A). With minimal momentum, curl the bar upwards towards your chin (B). Squeeze here and lower the bar under control taking a three count to bring it down. Repeat. Complete as many reps as possible, drop the bar, take 10 deeps breaths and then continue. Repeat in this fashion until all 100 reps are complete.

Session B

1. Push-ups on Dumbbell – 5 Max Effort Rest/Pause Sets

Remain in strong-plank position. With your core tight and hands on your dumbbells (A), bend your elbows to bring your chest to the floor (B). Keep your elbows close to your body as you push back up explosively. Perform as many reps as possible, take 10 deep breaths and perform another max effort round, take another 10 deeps breaths and complete one final effort— this is one set. Rest for two minutes between sets. Make a note of your reps, attempt to beat this next week.

2. Front Squat – Work to a Heavy 3-5 reps

With your feet at shoulder width, hold a barbell across your chest. Then, lift your elbows high to secure the bar on your shoulders (A). Maintain an upright torso and push your hips back, bending your knees until your thighs pass parallel to the floor (B). Stand back up to the start position. Once you can no longer control it’s descent over 2-3 seconds, the set is over.

3. Dumbbell Romanian Deadlifts- 4 sets of 8 to 15 reps

Stand tall with a pair of dumbbells at your sides, feet at shoulder width and glutes tensed (A). With a slight bend in the knees, push your hips back and slowly lower the bells towards the ground (B), pinching your shoulders back and maintaining a flat back. When you feel a stretch in your hamstrings, pause and explosively return to and upright position. Rest 90 seconds between sets.

4. Hanging Knees-to-Elbows- 4 sets of 20 reps

Hang from a bar with an overhand, shoulder-width grip. Ensure that your legs are straight, in front of your body, and that your feet are together (A). Engage your abs and pull down on the bar, raising both of your knees towards your elbows (B). Pause for a beat, before lowering your legs to the start position under control. Swinging is cheating. Rest 60 seconds between sets

Session C

1. Incline Dumbbell Bench Press- 5 sets of 5 reps

Laying on a bench inclined to around 30 degrees, press a pair of dumbbells into the air, locking out your elbows (A). Lower the ‘bells slowly until they touch your chest (B) keep your elbows at 45-degree angle, pause here before explosively pressing back up. Repeat. Rest two minutes between sets

Perform a few warm-up sets and then choose a weight that allows you to have 2-3 reps in reserve for the first set, but is a struggle to hit 5 reps with on the last few sets. If you manage all 25 reps with good form, go heavier next week.

2. Dumbbell Flyes- 5 sets of 10 to 15 reps (+ drop set)

Lower your bench to a flat angle, grab a lighter set of bells and press them up (A). With a slight bend in your elbows, slowly move your dumbbells outwards and down – towards the ground in a fixed arc. Keep your elbows at the same angle throughout, to avoid simply pressing the weight. Stop when you feel a deep stretch across your chest (B), before powering back up explosively. On your final set, once you can no longer complete another flye, switch to a pressing technique to eek out a as many more reps as possible.

B. Complete 4 Rounds of the Following Circuit, Rest for 2 Minutes Between Each Round.

1. Rear Delt Flyes x 10

Lay face down on a bench, or hinge at the hips until your torso is parallel to the ground, holding a pair of dumbbells with arms at full length (A). With a slight bend in your arm, raise your dumbbells up away from the ground, finishing in a ‘crucifix’ position (B). Pause here, squeezing your shoulder blades back and down before slowly lowering your dumbbells back to their starting position. Repeat.

2. Dumbbell Rows x 15

After your final flye remain prone on your bench or in your hinged position. (A). Maintaining a flat back, row both dumbbells towards your hips (B), squeeze your shoulder blades together and lower under control to the start before repeating. Control the bells and avoid moving your torso and using momentum to help.

3. Band Pull-apart x 20

Hold a band in front of your body, slightly below chest height (A). Keeping your arms straight, explosively pull the band apart, squeezing your shoulder blades together. When the band touches your chest (B). Reverse the movement and repeat.

Session D

1.Cable Chest Flyes (or Decline Dumbbell Flyes)- 5 Max Effort Rest/Pause Sets

Using stirrup handles attached to the high pulleys of a cable crossover machine, take one in each hand – your arms outstretched with a slight bend. Place one foot slightly forward, stretching your chest muscles, brace your core and pull the handles downward and across your body until they almost touch. Squeeze your pecs hard in this position (A). Slowly return to the start position and repeat. Perform as many reps as possible, take ten deep breaths and perform another max effort round. Take another ten deeps breaths and complete one final effort— this is one set. Rest for two minutes between sets. Keep the weight light on this one and focus on moving from a huge stretch into a big squeeze.
