You don't have to do the program at the full pace it suggests. You can work out less (2x / week rather than 3x / week). Rather than increasing the weight every time you finish all the reps, do the workout an additional time with the same set that you can handle. Don't move up as fast - rather than adding 2.5lb plates (5lb's total on the bar), add 1.25lb plates instead).

I quit after I seriously hurt my leg squatting. I did some more afterwards, but found myself getting a lot more out of other programs than weightlifting so I quit. The best thing I've personally found is alternating pilates (my posture sucks) with kickboxing (the workout-program kind with punching bags and gloves and a lot of other exercises, not the actually hitting someone kind).

Weightlifting made me stronger mostly in ways that didn't matter, and frankly made my posture worse. Other full body exercise programs made me stronger in ways that I can feel every day and make everyday activities more comfortable.

I've seen people who are actually training, and they never seem to do weightlifting alone. They always mix weightlifting with cardio with full body movements - the same kind of movement I see in exercise videos, I see high school and college sports teams doing on the field when training. Pro's don't do weightlifting by itself by the most part.

I might go back to weight training or I might not, if I do I'm planning on only doing 2 days / week and mixing it with other full body workouts (not on the same day of course) as pure weight training didn't achieve the goals of wanting to look better and get stronger in meaningful ways for me.

I do think that you would have a lot of trouble commuting by bike and doing 3x / week squats. They're exhausting, on the legs and lower back, but on the central nervous system as well. I was just wiped out by it.

For programs, Stronglifts was better balanced than Starting Strength (what I was trying to do) but both are exhausting - and imo not in a good way.

If you're mixing other exercise, I like the less intense progression of All Pro's better - but I didn't like that it had me doing the bench press and overhead press on the same day all the time as it hurt my shoulders:

I was starting to do Fierce 5:

Which was the best balance I had found so far, when I realized that I accomplished more of my personal goals with programs that weren't weightlifting (exercise videos, then stopped those and did pilates and kickboxing).
