Lower Body & Upper Body Workouts Critique

It looks like a pretty solid routine. If this is enjoyable and you are achieving benefit from it, then don't feel bad if you want to stick with it.

With that being said, I have a few suggestions for your consideration.

Maybe for every other lower workout, you can swap out the DB Lunges and DB Squats, and put in some Barbell Deadlifts? Maybe start with 4x6 or 6x4 at 50kgs? Deadlifts are an important compound lift that work a lot of muscles (hamstrings, glutes, core, upper back, etc.).

And maybe for every other upper workout, you can reduce your barbell row and bicep curls by one set, and add a couple of sets of chin-ups? Chin-ups will hit your back and biceps, as well as forearms (for grip strength). Grip strength can be very useful for basketball, however, when you start doing them, the soreness may impact your playing if you do it the next day. If chin-ups aren't an option, then I would use a lat pull-down machine. I think it's important, when working your back to include a row-type exercise and a pull-down exercise (such as the lat pull-down, pull-ups, chin-ups to name a few).

The tricep bench dips will probably start getting easy, and once you're hitting 15-20 reps per set, you'll want to add some weight. I think just adding more reps could potentially cause some shoulder injuries. You can either go to a dip station (where it'll be a bit harder), assisted dip machine (if one is available), or perhaps add a weighted vest?

Also, an observation about the box jumps. I think 4x10 is too many. Maybe someone can correct me if I'm wrong, but if you're working on building explosion, then you want to keep the reps low. Change it to 8 sets of 3-5 reps with 45-60 second breaks. I believe that with more reps, you're muscles start acclimating to endurance, rather than explosiveness. I think this would be more true to basketball style explosiveness as well? Usually, one might use those explosive muscles a couple-few times within a short period (getting a couple of rebound attempts, or firing off a couple jump shots, or scrambling for an errant pass or dribble?)

You can also change the sequence of some of your exercises too to make things more interesting. Start with BB Squats, for example. End with the calf raises. Start with overhead press and move into bench/triceps, then back and biceps.

Again, this is just some suggestions. I don't see anything wrong with your workout for your goals. Continued success to you! It sounds like you're commitment will get you to where you want to be.
