I will pass this information on written by Bret Contreras PhD.

Heavy Weight and Light Weight Sets Performed Close to Failure Produce Similar Gains in Muscular Hypertrophy
Bret Contreras, PhD Exercise Science

THIS (3) classic 2017 meta-analysis by Schoenfeld et al. concluded that although high loads lead to better strength outcomes and low loads lead to better strength endurance outcomes, high loads and low loads lead to virtually identical improvements in muscle mass. At this point in time, there are almost 30 studies showing this to be the case; it’s not up for debate. What is requiring more research is whether or not combining rep ranges (performing a variety of high, medium, and low reps) is superior to performing just one rep range for hypertrophy. Although a strong physiological rationale can be made, the research examining this question is equivocal.

According to THIS (4) classic study, if you go lighter than normal while focusing on maximally activating the muscle (rather than lifting the most load),you’ll see better hypertrophic results in the biceps.

What does this mean for you right now (during quarantine time)?

As long as you’re pushing your sets pretty hard, you can continue gaining muscle during this period of time, even if you’re doing mostly high rep training and not using heavy loads. Make sure to really squeeze the intended muscle in order to achieve maximum results.

Flexing (Isometrics) Can Build Muscle Just as Effectively as Free Weights in Beginners

THIS (5) monumental paper (I wrote about it in more detail HERE in 2016 ) showed that doing “air curls” while flexing hard produced similar hypertrophic (but not strength) adaptations. To elaborate, doing 4 sets of 20 curls with no weight and 30-sec rest between sets while just squeezing the biceps hard grew just as much muscle as doing 4 sets of 8-12 reps of dumbbell curls with 90-sec rest between sets in a progressive fashion starting at 70% of 1RM (study duration was 6 weeks…3 sessions per week for a total of 18 workouts).

And THIS (6) brand new paper showed that flexing in between sets built additional quad muscle (but reduced leg press maximal strength) compared to traditional training (not flexing).

What does this mean for you right now (during quarantine time)?

Bodybuilders have long touted the benefits of posing and flexing in the mirror. Not only does it help improve the mind-muscle connection, it also builds muscle. If you spend some time doing isometrics and just flexing your muscles for 10 minutes or so a few days a week, it can help minimize losses in muscle mass during this time and set the stage for further growth once normal training commences.

Single Leg Training Can Effectively Help You Maintain Lower Body Strength

There are currently 3 different studies investigating the effects of unilateral training versus bilateral training on squat strength. All 3 of them showed the same squat strength outcomes between both groups. In other words, doing Bulgarian split squats and step ups will improve your squat strength just as much as doing squats will. Don’t believe me? See HERE (7),HERE (8) and HERE (9).

What does this mean for you right now (during quarantine time)?

Many lifters and coaches mistakenly underestimate the transfer of single leg training to double leg training. Why wouldn’t it transfer well; it’s the same movement pattern?! My buddy Ben Bruno ( only does single leg training; he never does squats but could hit a 365lb front squat (which is double bodyweight as he weighs 172lbs) on any given day.

But the caveat is that his single leg training is absolutely brutal.

Now, during the quarantine you may not be able to perform heavy BSSs or step ups, but you can definitely hammer your legs. I don’t care how strong you are, there’s always a challenging single leg variation (pistols, skater squats, super high step ups, single leg box squats, etc.). Trust me, if you train hard during these times, your squat strength won’t suffer too much.

Push Ups Can Effectively Help You Maintain Upper Body Pressing Strength

THIS study (15) and THIS study (11) both show that push ups and bench press share very similar movement patterns and levels of muscle activity. That’s all well and good, but three studies to date have shown that push up variations transfer similar to bench pressing compared to actual benching. See HERE,(12) HERE,(13) and HERE (14)
What does this mean for you right now (during quarantine time)?

It’s obvious that push ups could help you maintain your bench press strength due to their similarity in kinematics. And even if push ups are super-easy for you, you can figure out more challenging push up variations to help you retain more maximal bench strength. For example, band resisted push ups, weighted push ups, between-bench feet-elevated push ups, self-assisted one-arm push ups, etc. If you train hard and intelligently during these times, you may be pleasantly surprised when you find yourself back at the gym and find that your bench has remained strong.

Mental Imagery and Imagined Contractions Can Help You Maintain Strength

THIS (15) classic systematic review paper by Slimani et al., published in 2016, summarized the findings of mental imagery training. Performing imaginary workouts have been shown to mitigate strength losses during detraining in addition to boosting strength during normal training times.

What does this mean for you right now (during quarantine time)?

I used these methods while rehabbing from my glute injury last year (“The Glute Tear Heard Round the World” lol). Consider injecting some mental imagery training into your routine while you’re under quarantine. Use both internal and external imagery and go through the motions while you do it and activate the proper muscles – this leads to better results. You can hold onto more of your maximal strength if you adopt some of these strategies.

Good post man. This is something that some people have known for years. I was forced into it because of reoccurring back (lower/middle),neck, shoulders and hip problems. You wouldn't know it by looking at me but I have a lot of problems that if I don't stick to an injury prevention type program, I'm a mess.

I haven't messed with anything heavy in years. I'm mainly running reps, super slows, holds, negatives, supersets, trisets. giant sets, etc... it's not something you do overnight. It's something you have to get used to, you have to find that sweet spot where your not over or under working. It's easier than most think if you know your body. You know what it feels like on that last rep when doing heavy stuff. No different, just takes longer to get there. If you have mind to muscle in your bag of tools it's a different experience.

If anyone is worried about not having enough weight, spending a little more time will get the job done.
