Can you still build muscle with at home bodyweight workouts?


"Can you still build muscle with at home bodyweight workouts?"

One of the great misconceptions of not having access to gym equipment and heavy weight training is that you will not be able to build muscle.


This is absolutely not the case! You only have to look as far as the popular calisthenics movement (based on bodyweight exercise) or gymnastics to see some truly impressive physiques.


However, the approach you take to build muscle will differ at home as the methods you use to drive muscle growth may not be as straightforward as those we use in regular weight training. It's no longer as simple now as increasing weight on the barbell or changing the resistance on the machine.


Understanding the nature of how we develop muscle comes first; if we know how to build it, then we know what aspects of our bodyweight training program we can adapt, change or even look for new elements to introduce to continue to build that hard-earned muscle.





What causes muscle growth?

Muscle growth or "muscle hypertrophy" has been proposed to occur due to three main contributing mechanisms; mechanical tension (i.e. resistance applied to the muscle), metabolic stress (which refers to the accumulation of metabolites, produced by metabolic processes associated with exercise, that give you that "burning" feeling) and muscle damage (which is the pain and or swelling associated with exercise induced muscle damage).


When designing a bodyweight workout with the primary goal focused around muscular hypertrophy, basing it on movements, rep and set schemes, time under tension and other approaches that take into consideration these three primary contributors to muscle growth will provide the best results.


Of course, it isn't just what we do during our programmed exercise that will impact muscle growth; adequate nutrition (which we've covered in a previous "at home" focused article), sleep and stress management will all impact how successful a hypertrophy program is.


How to implement these concepts into home bodyweight workouts?

Firstly, we have to consider what is available to us and which of the three contributors to muscle hypertrophy we should focus on based on equipment availability.


Mechanical tension

The obvious limitation is going to be how much we can progress within mechanical tension; with limited gym equipment and the focus of our training program being predominantly bodyweight exercises, there is only so much you can do which is focused around increasing load on the muscle.


Adding in a resistance band can help increase tension/load as can altering movement patterns or increasing the difficulty of exercises you do. An example of this would be progressing from doing a push up with your knees on the ground to a traditional push up whereby the feet and hands are the only point of contact with the ground. Another example would be doing tricep dips on a chair and eventually progressing into dips whereby you are supporting your entire bodyweight.


You could also look to incorporate new movement patterns, such as handstand push-ups and split squats from a chair / elevated surface. Safety is paramount here and so be mindful to have someone there to support you if you are doing more challenging movements, especially those like the handstand pushup whereby your neck could be at risk. Complex moves such as these should only be practiced by those with extensive strength training experience.





Metabolic stress

So, there are several ways you're going to be able to increase metabolic stress at home; upping the reps, "supersets / giant sets", reducing rest times, incorporating a HIIT workout or restricting blood flow to the focused muscle group.


Why does time taken between reps matter? With muscles continually contracting and relaxing, a blood pooling effect is created within the muscle. This causes the cells within the muscle tissue to swell which we may know as the "pump".


This, in turn, results in restricted blood flow to the muscle (which may be referred to as occlusion) which means there is a lack of oxygenated blood being able to fuel the muscle during the continual contractions. This leads to a large build-up of metabolites within the muscle. The resulting metabolic stress placed on the muscles has an anabolic effect leading to molecular signalling and an increasing hormonal response by the body driving hypertrophy and possibly muscle gain (when fuelling and recovery supports this).


Occlusion training in of itself is a separate entity, and has been used to induce hypertrophy / sustain muscle mass using much lighter loads but increasing the number of reps performed.


Whilst this has been shown to be of particular benefit in clinical settings, we could also use these same principles at home. Applying some kind of restriction (like a tourniquet or tightly wrapped material) to the blood flow to the muscle you're focusing on and using a light weight (even something as simple as a kilo bag of sugar) for many reps can help you achieve a similar effect. If you want to incorporate a bodyweight exercise, a pushup would be an incredibly challenging bodyweight movement when incorporating occlusion principles.


Muscle damage

I think we've all experienced the dreaded DOMS (delayed onset muscle soreness) a day or two after a training session. The result of micro tears in the muscle following exercise, it's a common sensation many experience during the recovery and adaptation phase following exercise.


Whilst not everyone who achieves hypertrophy and strength increase will experience DOMS it is a noted indicator that hypertrophy is being achieved. It should be noted that the severity of DOMS experienced does not correlate with more hypertrophy being achieved; those naïve to exercise or introducing new stimuli to the muscle (load, volume, exercise selection etc.) may experience more DOMS until they become acclimated.


Eccentric movements, or the stretching of the muscle in focus, induces the most damage, so be mindful of this when considering what movements to incorporate.


For home workouts, focus on slowing down the "stretch phase" of the movement will help achieve even more hypertrophy. Try incorporating counts into the stretch phase; counting down from five or ten for example. An example of this would be a slow and controlled body weight squat, lunge or even pushup!


It'd also be worth separating movements focused on muscle damage and increasing metabolic stress; melding the two may lead to compromises in technique and increased risk of injury!





Conclusion

Building muscle at home with just bodyweight workouts is totally achievable, it just requires a bit of adaptation to your training program.


Knowing what drives muscle hypertrophy will help us focus on the adaptations that will give us the most "bang for our muscle building buck".


Focusing more on metabolic stress and muscle damage may be a better strategy when our ability to increase mechanical tension is limited. It's not always about training harder, training smarter can help you get ahead too!
