One more comment for the fact that it's best to focus on the journey, not the destination.
It sounds like COVID hit you hard, perhaps investing in some home gym equipment would be good. I have a bench, bunch of plates, the bowflex 552s and 1090s, a power tower, weighted vest, bands, and elliptical at home. Now, I have slowly accumulated those things over the course of the last 15 years, but damn I get can a SHIT LOAD done right in my workout room at home. I enjoy working out and like
@Eman the only person I really compare myself to is the one in the mirror. I want to be the best person that
I can be, not someone else.
I don't have an instagram, no twitter, login to facebook like 4 times per year, no tiktok or any of that shit. I have reddit, but I don't follow subs where I am exposed to a bunch of other people's physiques, whether that is male of female. The last thing I want is to just feel like I am not good enough, not only does it just not feel good mentally, but it also zaps your confidence which has a downstream effect on motivation IMO. For some people it might motivate them to bust their ass even harder, but idk, a lot of people it deep down it is secretly a little demotivating and reinforces negative psychological cycles and bad habits like eating worse or using drugs.
Just find what works for you, embrace it. Make small-to-medium sized lifestyle changes here and there so you can sustainably grow and improve your physique and strength. If your physique concerns are due to fat accumulation, then change what groceries you buy. If it is muscle loss, well..that is an easier fix to be honest, just get back on the bicycle and start lifting again, that muscle will be back in no time. Those myocytes are still there, waiting to grow again!
IMO your next steps are: identify exactly WHY your physique has gone downhill, then list out the options you have to reverse that trend. Take action on them. It may be getting some home gym equipment, it may be changing the foods you buy and eat, it may be ensuring you're getting enough sleep, it may be starting a new lifting program or going for bike rides again to get some cardio in (if you are northern hemisphere and spring is coming soon

).
You aren't going to wake up one day and be like "Hey, I am finally a mass monster, I am happy in all aspects of life and my physique is perfect and it literally could never be better!" The human brain will always find something wrong, some spot where your physique isn't good enough, some muscle that isn't as defined as the other guy you're looking at on insta or competing against on stage.
Don't fall into that trap. In the end, research has shown that the people who are happiest in life have found joy in the PROCESS of living. The PROCESS of self-improvement. Life is about living, so live it. Fall off, get back on. I have fallen off more than a couple times, too, in one way or another. You don't feel good about your body? Fuckin take action to fix those feelings! You'll find that the simple act of
doing something makes you happy and feel good too. The journey
is the destination.
