Just come back slowly and have patience you’ll get them back no time

well it may work but also it may be too difficult it is probably better to work 2-3 sets of hardest varation in a range of 10-12 reps

hi there do not be desmotivated because you cant do a pullup i myself wasnt able to do one at the start. So do push pull leg push pull leg split. you can do puhs rest pull rest leg rest at the start training 3 times a week or if you can train 5 times a week. So push day. choose the hardest progression your working on then move on to easier variaiton and finish off with core exercises. when you hit 15 reps of a progression you will be ready to move on to the next progression. so push: pushups please make sure youre back is not arched. your elbows do not flare out and keep core tensed. do three sets of pushups first two sets going almsot to failure like you can not do one more so if you can do max 8 pushups do 6 pushups do this for two sets and for the third set do max push ups full failure. rest 2-3 min in between sets. then move on to 3 sets of knee pushups the first two sets almost failure and then third set full failure. finish off with core so you can do leg raises wether hanging or lying down. do three sets of max then 2-3 of max hold of hollow body hold. pull day same principle so three sets of hardest one so if you can not do one work on negatives jump up on bar and lower yourself down slowly do three sets of 5-8 reps then do three sets of australian rows wether legs bent or fully extended do first two sets almsot failure and then third set failure. finish with same core workout or change it up with other exercises you want leg day work on squats trying to progress to pistol squats do three sets almost failure and then if you want add reverse nordic curl 2 sets till failure here it is optional to work core. do this routine push day -´pull day- leg day- rest- push-pull-leg- or push-pull-leg-push-pull. do it however you want but do let each muscle group rest at least 24 hr. hope that helps if you have any questions just ask.

Wow very cool man awesome

So you do two sets of each exercise each day like all of them one single day?

It can work but it may be too much on your body or eat least change it to pushing exercises to push day and so forth and also really need a very good warmup before starting including body circulation and easier progression of the exercises. And if you do decide to do this then every 3-4 weeks have a deload week in order to not overtrain
