My #1 priority is to achieve my goals and have fun. If that means I die earlier so be it. I do exercise in ways I find fun, but I will not go to a gym and lift weights just because it increases my chances of living long enough to enjoy my pension.
The real challenge in life is not to live the longest, but to have lived a life worth living.
Strength training can be as simple as doing one of squats, pushups, or pullups every day. Work towards 2-3 sets of 10-20 reps. Add weight (or reduce assistance) as necessary.
You've just made a huge difference in how your body feels, and it takes as much time each day as brushing and flossing your teeth.
I definitely think all homes should have a pullup bar. They can be had cheaply, and easily attached to doorframes. A good way to add quickly pulling motions for $30.
I may try higher rep dumbbell squats, I've been looking for a way to workout purely at home. Is there a deadlift targeting version too?
I also prefer using one dumbbell held with both hands (e.g. https://www.youtube.com/watch?v=x3siyLMUr_Q) to holding a dumbbell in each hand. I think its easier to maintain good form engaging the posterior chain, but ymmv.
I've never liked deadlifts personally, so I'm a bad person to ask. I tend to target lower back with back extension machines, or supermans if no machines around.
I exercise by riding my mountainbike up and down hills. Which I find to actually be fun instead of feeling like I'm wasting my time.
I've also done team sports during my student years, which was also a case of getting exercise while having fun doing it.
Some people have fun doing gym exercises and that's great for them. However I don't think you'll ever convince the majority of the population to hit the gym or do home exercises just to stay healthy. We should find more ways to make all kinds of sports more accessible, so everyone can find the method of exercise that they enjoy.
Btw I agree with him, I think that's what you really want, but you want your fun. Not fun as perceived by other people. It does not necessarily mean pleasure.
