It's nearly impossible to work on your "pull" strength without some kind of equipment.
Deadlifts are considered the best lower body pull exercise.
And pull ups are considered the best upper body pull exercise.
If I may, deadlifts mean shit in construction. Not gonna help you carry something (usually 50 to 75 lbs) up a ladder.
Push ups will help upper body plus if you can do enough reps, then walk out a 3-5 minute cool off. It will help cardio.
Planks ( the thing where it stresses your core) would help alot on mid torso and lumbar strength.
Tell ya what, get a job with a local CATV company, they pay well, will have you packing ladders, and crawling on your belly with toes and elbows, if you stay long enough you could climb poles with hooks ( climbers) make sure they provide a Buck Squeeze for safety. Do that while you pay off the next 10 months. You will be stronger that if you spent money on equipment plus getting paid for it.
Anyhoo. IF you think I am full of XXXX I would gladly take a plank challenge to prove my point. I am close to 53 yrs old. My nephew tried to show me up, (20 years younger) I asked how much longer would he like me to hold after he couldn't stay straight.
TBH I am rooting for you. But using credit for strength training is ridiculous.
