15–20 minutes a day · At home · No gym required. You don't need an expensive gym or an hour of free time to stay fit. These five exercises work your major muscle groups, improve balance, build strength, and support cardiovascular health — all in 15–20 minutes at home, with no equipment whatsoever. The research backs this up: a [2021 review in the Journal of Exercise Science & Fitness](https://doi.org/10.1016/j.jesf.2020.11.003) found that bodyweight resistance training performed 3–4 times per week produced significant improvements in muscular strength, endurance, and body composition comparable to gym-based resistance training in previously sedentary adults. The barrier to entry is zero. The only requirement is showing up.

Squats

Muscles worked: quadriceps, hamstrings, glutes, core. Stand with feet shoulder-width apart, toes pointing slightly outward. Lower yourself as if sitting back into a chair, keeping your chest tall and knees tracking over your toes. Descend until your thighs are parallel to the floor (or as low as comfortable), then drive through your heels to stand. Aim for 3 sets of 12–15 repetitions. Why it matters: squats are the most functional lower-body movement in human life — every time you sit down and stand up, you are performing a squat. Maintaining squat strength is one of the strongest predictors of independence and fall prevention in older adults. A [2014 study in the European Journal of Preventive Cardiology](https://doi.org/10.1177/2047487313480284) found that the ability to rise from the floor without using hands was independently associated with all-cause mortality in adults aged 51–80.

Push-ups

Muscles worked: chest, shoulders, triceps, core. Begin in a high plank position with hands slightly wider than shoulder-width, body forming a straight line from head to heels. Lower your chest to the floor by bending your elbows at roughly 45 degrees from your torso, then press back up. If full push-ups are too challenging, perform them from your knees — this is not a regression, it is a progression point. Aim for 3 sets of 8–12 repetitions. Why it matters: push-ups are a reliable proxy for cardiovascular health. A [2019 study in JAMA Network Open](https://doi.org/10.1001/jamanetworkopen.2019.0589) found that men who could complete more than 40 push-ups had a 96% lower risk of cardiovascular events over 10 years compared to those who could complete fewer than 10. Upper-body pushing strength also protects the shoulder joint and supports posture in a desk-bound world.

Glute bridges

Muscles worked: glutes, hamstrings, lower back, core. Lie on your back with knees bent and feet flat on the floor, hip-width apart. Press through your heels to lift your hips toward the ceiling, squeezing your glutes at the top. Hold for 1–2 seconds, then lower with control. Aim for 3 sets of 15 repetitions. Why it matters: the glutes are the largest and most powerful muscle group in the body, yet chronic sitting causes them to become inhibited and weak in most adults — a condition sometimes called 'gluteal amnesia.' Weak glutes are a primary driver of lower back pain, knee pain, and hip dysfunction. Glute bridges directly address this without loading the spine, making them safe for almost everyone, including those with existing back pain.

Plank

Muscles worked: core (transverse abdominis, obliques, rectus abdominis), shoulders, glutes. Begin in a forearm plank position — elbows directly under shoulders, body forming a straight line from head to heels. Engage your core by drawing your navel gently toward your spine, and squeeze your glutes to prevent your hips from sagging. Hold for 20–60 seconds. Aim for 3 sets. Why it matters: the plank trains the core in its primary function — stabilisation under load — rather than the flexion-based movement of crunches. A strong, stable core reduces injury risk across all physical activities, improves posture, and protects the lumbar spine. [Research published in the Journal of Strength and Conditioning Research](https://doi.org/10.1519/JSC.0b013e318225a8c6) found that core stability training significantly reduced the incidence of lower back pain in active populations.

Walking lunges

Muscles worked: quadriceps, hamstrings, glutes, calves, core. Stand upright and step forward with one foot, lowering your back knee toward the floor until both knees form roughly 90-degree angles. Push through your front heel to bring your back foot forward into the next lunge. Continue alternating legs for 10–12 repetitions per side, 3 sets. Why it matters: lunges train single-leg strength and balance simultaneously — a combination that directly translates to walking, climbing stairs, and every activity that involves moving on two legs. Single-leg training also corrects strength imbalances between sides, which are a common source of injury in runners and recreational athletes.

Putting it together: a 15-minute routine

Perform each exercise back-to-back with 30 seconds of rest between exercises, and 90 seconds between rounds. Complete 2–3 rounds depending on your available time. Squats (12 reps) → Push-ups (10 reps) → Glute bridges (15 reps) → Plank (30 seconds) → Walking lunges (10 reps per leg). This sequence is designed to alternate between lower-body, upper-body, and core-dominant movements, which minimises local fatigue and allows you to maintain quality across all five exercises. As you get stronger, increase repetitions, add a fourth round, or slow the tempo of each movement to increase time under tension.

How often should you do this? For general health maintenance, 3 sessions per week is sufficient — this aligns with [WHO physical activity guidelines](https://www.who.int/publications/i/item/9789240015128), which recommend muscle-strengthening activities on at least 2 days per week for adults. For those seeking more significant strength or body composition changes, 4–5 sessions per week with progressive overload (more reps, slower tempo, or added resistance via a backpack or household items) will produce faster results. Rest days are not optional — muscle adaptation occurs during recovery, not during the workout itself.

⚕️ Note: If you have existing injuries, joint pain, or cardiovascular conditions, consult a healthcare provider before beginning a new exercise programme. Most of these exercises can be modified for lower-impact versions — ask a physiotherapist for guidance specific to your situation.
