Skip the gym — instead try this trainer’s 4-move bodyweight workout to sculpt your arms and core

What if we told you that you could train your core and arms in one session with just four exercises? And it gets better, no equipment is required. That’s right, no dumbbells, no resistance bands, just you, one of the best yoga mats for padding if you need it, and this trainer-led routine.

We have trainer Sandy Sklar to thank for this routine, a fitness instructor you need on your radar if you want to keep staying fit and strong simple, and at home with minimal to no equipment involved. This particular routine of hers is all about strengthening and sculpting from the waist up.

Sklar has shared demonstrations of her performing each move over on her Instagram, which you can view below. All you need to do is copy her form, factor in rests (albeit short rests) work through the circuit, and aim to complete three to five sets depending on how much of a pump you are looking for.

Watch Sandy Sklar's 4-Move Core and Arms Workout

• Sphinx (plank) press (modify on knees) x 10
• Push-up to shoulder tap x 10
• Commando plank (plank ups) x 10 total (up + down = 1 rep)
• Modified v-sit with front raise (slow and controlled) x 30

Sklar's routine combines plank variations, push-ups, and controlled core movements like the v-sit to strengthen both the arms and core. The plank-based exercises not only work the shoulders, triceps, and chest but also force your core muscles to stay engaged in order to keep your body stable and properly aligned. Meanwhile, the modified v-sit with a front raise adds an extra challenge by targeting the abs and working the shoulders at the same time.

You'll perform 10 reps of each exercise, except for the final move, which is done for 30 seconds. Focus on slow, controlled movement rather than rushing through the reps. When fatigue kicks in, it’s tempting to speed up so that you can collapse onto the mat quicker for a rest. However, maintaining proper form and increasing time under tension—the amount of time your muscles stay engaged during each rep—can lead to greater strength gains.

You might resent Sklar for keeping the rest periods short, but this is intentional. Less rest increases metabolic stress and keeps your muscles working for longer, which can help improve endurance and muscle definition. It also keeps your heart rate elevated, adding a cardio element to the workout.

If you prefer to train without weights or gym equipment, then this circuit is a great starting point. The exercises included in the routine work more than one muscle group at once and improves things like stability, endurance, and muscle definition. Even if you already strength train regularly, this routine works well as a finisher to challenge your core and upper body after a workout.
