As I mentioned in another thread I might have a muscle imbalance with a weak posterior chain. I want to develop better posture in the simplest way possible. I train bjj 3-4X per week. I also walk, hike, bike, rock climb, swim, and stretch in moderation. I would like to add a few exercises to help develop my calves, hamstrings, glutes, and lower back.

What exercises would you guys recommend? I don't need any bulk or muscle definition. I'm looking for functional strength, better posture, and injury prevention.

I am joining a club for a couple of months that has a full weight set. I don't really like weights and have lifted very little in my life.

They have an " air rowing machine"? that I would like to try. Maybe some dead lifts, pull ups, exercise ball, calf raises, and low back exercises.

I'm trying to keep it as simple as possible. Something that I can integrate into my busy schedule without too much regiment or structure.

Thanks in advance.
