Biomechanical cues verified by the PlanWorkouts Science Review Board under CSCS editorial oversight; see our editorial standards.
The Isometric Wipers is a compound chest movement designed to train the Pectorals with direct engagement of the Triceps, Core.
Transverse plane horizontal adduction of the shoulder combined with elbow extension. Peak mechanical stretch occurs when pectorals are fully lengthened at chest level. Scapular retraction is vital for shoulder joint safety. Executing this with strict form maximizes muscle fiber recruitment while protecting joint structures.
Quick Exercise Facts
Target Muscle Activation
A windshield-wiper style isometric hold trains the chest and shoulders through sustained tension at various angles rather than dynamic movement, similar in spirit to an isometric chest squeeze but moving through a small arc. It's a light, equipment-free accessory move rather than a primary chest builder.
How to Do the Isometric Wipers
- Begin lying flat on your back on a mat or bench.
- Stretch your arms out to the sides, perpendicular to your torso.
- Brace your core and raise both legs off the floor, keeping them together and straight.
- Slowly lower your legs to one side under control, aiming to touch the floor with your feet.
- Pause briefly, then use your core to bring your legs back up to the starting position.
- Repeat the movement lowering your legs to the opposite side this time.
- Keep alternating sides for the desired number of repetitions.
Recommended Sets & Reps by Training Goal
70–80% 1RM · 90–120s rest
85%+ 1RM · 2–3 min rest (Calc 1RM)
50–60% 1RM · 45–60s rest
Biomechanical & Joint Load Cues
Transverse plane horizontal adduction of the shoulder combined with elbow extension. Peak mechanical stretch occurs when pectorals are fully lengthened at chest level. Scapular retraction is vital for shoulder joint safety.
Common Mechanical Mistakes & Form Errors to Avoid
- Excessive Elbow Flare (90°): Flaring the upper arms directly perpendicular to the torso pinches the supraspinatus tendon against the acromion. Tuck elbows to roughly 45–70 degrees.
- Loss of Scapular Retraction: Allowing shoulder blades to slide forward off the bench shifts mechanical tension off the pectorals onto the delicate anterior deltoids.
- Bouncing Off the Sternum: Using ribcage recoil to bounce the load bypasses the critical bottom turnaround stretch where muscle protein signaling is highest.
Proper Breathing Patterns & Core Engagement
Inhale deeply during the lowering (eccentric) phase while pinning shoulders back. Exhale forcefully through the concentric pressing phase past the friction zone.

Injury Modification & Joint Safety
Lifters with anterior shoulder impingement or AC joint inflammation should restrict elbow flare to 45–60 degrees or substitute with neutral-grip dumbbell presses. If joint irritation persists, immediately stop and substitute this movement with another exercise from the Chest exercises category.
Muscles Worked
The Isometric Wipers primarily targets the Pectorals, with Shoulders as the primary synergist muscle group, along with the Triceps, Core.

FAQ
- What muscles does the Isometric Wipers work?
- The Isometric Wipers primarily targets the pectorals as the primary agonist. Synergist assistance is provided by the shoulders along with the triceps, core. Maintaining strict biomechanical alignment ensures maximal tension remains focused on the intended muscle fibers rather than shifting to surrounding stabilizer joints.
- What equipment do I need for the Isometric Wipers?
- The Isometric Wipers is performed using no equipment — just body weight. Ensure all equipment is securely positioned with collars or safety pins locked before loading working sets. If you train in a home gym or minimal setup, explore our equipment-free and resistance band alternatives below.
- What is the most common form mistake on the Isometric Wipers?
- The most frequent error is excessive elbow flare (90°): Flaring the upper arms directly perpendicular to the torso pinches the supraspinatus tendon against the acromion. Tuck elbows to roughly 45–70 degrees.. Controlling the 2 to 3-second eccentric lowering phase ensures maximal hypertrophic stimulus while shielding connective tissue.
- How many sets and reps should I perform on the Isometric Wipers?
- For muscle hypertrophy and size, aim for 3 to 4 working sets of 8 to 12 repetitions at 70% to 80% of your 1RM with 90 to 120 seconds rest. For absolute strength development, prioritize 4 to 5 sets of 3 to 6 heavier reps with 2 to 3 minutes rest.
- What's a good alternative to the Isometric Wipers?
- If you don't have access to the space or setup it needs, the Barbell Bench Press targets the same pectorals using barbell instead. This alternative replicates the same joint angle and movement plane while allowing you to train effectively with different available gear.
