7 best YouTube workouts to build muscle in no time, according to PTs

Why are YouTube workouts good for building muscle?

It's not complicated - when it comes to building muscle, the primary way to achieve this is through strength training. There are several different forms of strength training, but they can (almost) all be done at home, via a YouTube workout.

Thanks to the pandemic, there's more content available online than we'll ever have time to sift through, so you're bound to find a style of training and an instructor that suits you, and as we know, consistency is key when it comes to making fitness and strength gains - so enjoying your workouts is half the battle.

"Building muscle from home is entirely possible, and with the right guidance and dedication, you can achieve significant strength and muscle gains without ever stepping into a gym," agrees Rowan Clift, training specialist at AI-based fitness and lifestyle coaching app Freeletics. "The key lies in following a structured workout program that incorporates progressive overload, effective exercise variations, and proper recovery. Ideally you'll follow a tailored plan that adapts to your fitness level, ensuring you continuously challenge your muscles for growth."

What are the benefits of YouTube workouts for building muscle?

First and foremost, YouTube workouts are super convenient - there's no commute or waiting for equipment, and you can work out at your own pace without feeling self-conscious (no gymtimidation) and if you want to work out in your pyjamas, no one is going to judge.

Practicalities aside, there are lots of other reasons to give YouTube workouts a go.

1. They're efficient

Just think - the time you save getting ready and travelling to the gym, you can dedicate to a proper warm up and cool down - which, let's face it, even the most diligent of exerciser is tempted to skip when we're short on time. But more than this, even without equipment, home strength workouts are excellent for targeting multiple muscle groups at the same time.

"Depending on the equipment you have available to you at home, it might be the case that your home workouts are bodyweight based," notes Clift. "Many bodyweight exercises, like squats, push-ups, and lunges, target multiple muscle groups simultaneously. This leads to greater overall muscle activation and development. For example, a push-up not only works the chest but also engages the shoulders, triceps, and core, making it a highly efficient way to build strength."

2. They improve functional strength

"Bodyweight exercises also improve functional strength, which means the muscles you build are not just for aesthetics but can also enhance your day-to-day movements," says Clift. "By performing exercises that mimic real-life actions, such as squatting, pushing, and pulling, you develop strength that transfers to daily activities and improves overall mobility."

3. They can be tailored to all abilities

As we touched on above, the key to building muscle is to apply the principle of progressive overload, which is easily replicated at home. "Progressive overload is the key to building muscle," Clift tells MC UK. "This can be done by increasing the number of repetitions, adding more sets, or changing the intensity through variations (e.g., progressing from regular push-ups to decline or explosive push-ups). Resistance can also be added with items like resistance bands, weighted vests, or using household objects."

There are so many options available, it's simple to constantly adapt your workouts to challenge your body.

4. They offer flexibility

Last but not least, home workouts offer flexibility, both in terms of time and structure.

"You can tailor your routine to fit into your daily life, making it easier to adapt your workouts around other commitments," notes James Brady, personal trainer at OriGym. "This flexibility means you’re less likely to skip sessions, maintaining the consistency needed to build and sustain muscle growth."

Who are YouTube strength-training workouts best for?

While the experts are clear that home strength training workouts are suitable for all abilities, they all noted that, if you're new to building muscle, it's worhth investing in a few sessions with a pro to start with.

"While muscle-building workouts can benefit most people, they may need to be tailored to suit individual needs, fitness levels, and health conditions," cautions Brady. "Beginners or those with limited experience should start with simpler exercises and lighter intensity to build strength safely and avoid injury. People with medical conditions or physical limitations should consult a healthcare professional or a trainer to create a routine adapted to their abilities."

How often do I need to work out to build muscle?

"To build muscle, aim to work out three to six times per week, depending on your fitness level and recovery needs," says Brady. "Beginners can start with three to four sessions weekly to allow for proper recovery, while more advanced lifters might train five to six days, targeting specific muscle groups.

"Don't forget to ensure 48 to 72 hours of recovery before working the same muscles again, as rest is essential for growth. Pay attention to your body and include active recovery days to prevent overtraining and support consistent progress."
