I got something like this: resistance bands
I hung them around my pull up bar (all of them combined) I think it equaled about 80 lbs of resistance.
I kneel on them while I do pullups so that it "removes" 80 lbs of my weight. Work on perfect slow form for however many reps say 20. When you can do 2 sets of twenty remove a band so you on have 65 lbs off, rinse and repeat until you can do your own full bw then work on weighted reps.
I use youtube videos for all different kind of workouts (HIIT, yoga, pilates, Tabata, cardio dance classes) and have a set of resistance bands that can be anchored at different heights into a door frame for strength training. Similar to this set.
Sounds like a bunch of excuses lol. You don’t need to run to get in shape. Unfortunately everyone thinks that’s the only way when it’s the worst way. As for hard to do exercise in pandemic. For $27 u can do a full body workout in any room in your home.
Edit: or down vote me, stay fat, and die of Covid. To each their own
Mine are identical to this just a different brand cause I'm in Canada:
It comes with different bands with different resistance levels. If you manage to progress through them all then you can even combine more than one band to add up resistances.
