Are you stuck at home and not able to go to work? Or are you working but forced to go straight home cause all businesses in your area are currently closed? I can share what has helped me through this. And I'll give you some details. I did take much of april basically off, not working out more than once a week at best. probably just mental struggles of dealing with covid, then planning a small covid wedding with my wife back in May.
Dietary:
We food prep every sunday for the entire week. so I have 10 tuperware type containers in the fridge sunday night with all of my breakfasts and lunches for the week already made. We could dinner together every night and cook healthy.
Supplements: I use modern BCAA+ flavored powder in a 24oz hydroflask every morning at work that I sip from around 7am till 10am. I try to refill it with regular water at least once, if not twice a day. I take some sorta of male-focused supp as well. Either tribulus, horny goatweed, or something of that nature and arginine. I take fishoil when my joints are sore but should be more religious about it.
workout: I have been using the runkeeper app and told my self I'm "accumulating" miles. I'll try to run a 1.5 mile warmup 4x per week at home (been irregular with that) because it's "something" before I workout.
at home I do have a squat rack we borrowed from our gym on my front porch so I'm lucky. With that, I do basically one main lift (either power or oly) and then I write a wod for that day that compliments the lift and I try to change the time domain each time. If today I do a 20 minute wod, then tomorrow I'll probably do a 9 minute wod, or a 3minute + 3min rest + 3min wod.
ONe wod that only required a kettlebell
10 air squats
9kb snatch right arm
10 push ups
9 kb snatch left arm
10 minute amrap
this one only required a jump rope:
100 double unders
21 burpees
75 double unders
15 burpees
50 double udners
9 burpees
for time
Another you could do is set an EMOTM timer. mark off 25 yards from your starting point
15 minute EMOTM
50 yard sprint
max effort burpees
count total burpees after you're completed, hitting that 50 yard sprint at the beginning of every minute.
if you don't have any equipment you can mix up the emotm approach with a million other things.
EMOTM
10 burpees
max air squats
etc etc etc
good luck man, hope anything here helps.
