I LOVE the stability ball. The possibilities of what you can do with it are endless. It can be a full body workout with no impact!

Pretty much anything you can do with free weights, you can adjust to the stability ball - so use your imagination. Here are just a few exercises I do. Of course, when you are comfortable enough, and have complete control, you can kneel on the ball and do weight exercises and then stand on it

But one step at a time! If the directions are not specific enough, maybe you could go to the Sissel site and see pictures - I think JP has pictures on his site as well (although his moves are WAY advanced).
These are some of my notes - of course, they make complete sense to me....hope they do to you as well.
Basic
To make sure ball is proper size – sit on ball with knees bent – there should be a 90º angle with your knees
Sit with a neutral spine – head over shoulders over hips
Warm-up
Balance by lifting one leg then the other – march – kick
Stand behind ball – toe on ball – rotate left and right
Hold ball – push left and right
Lift ball overhead and lower
Abs (on ball)
Lie on Incline – lift upper body – ball should be in middle of back
Move body up a little – less support – harder to lift
Lift bringing right shoulder to left hip (across body) – lift to the middle the rotate to side
Lie in Bridge Position – hold arms overhead and take to the left and right
Lie on Side on Ball – either one knee down or feet staggered or feet stacked – arm over head and crunch obliques
Lie on side – lift top leg up and down -- then combine this with oblique crunches
Lie on side – bend top leg kick forward - bend kick behind
Stability Exercise
Lie on ball on belly – hands on floor – lift one arm – lift opposite leg – then lift arm and opposite leg together – lift one arm and both legs
Lower Back and Push-up
Belly on ball – toes apart on ground (for stability) – hands behind head or back – lift upper body
Lie on belly in a “V” position – elbows on floor – hips towards back of ball – lift legs up
Prone position – ball at either hips, knees, or ankles – push-ups – try lifting one leg
Prone position – roll ball in – hips up
Weights – 10 reps – 3 sets – medium/heavy weight
Lie with head on ball in bridge position – bench press then fly – come to incline and crunch with weights on chest in between sets
Incline position – bench press and bicep curls
Sit on ball – overhead press and bicep curls – or hold weights hands facing you – then overhead press hands away from you – or hammer curl and overhead press
Lie in bridge position – tricep lifts then tricep extensions (one weight)
*** You can also do all of the above exercises while lying on the floor with feet on the ball in a bridge position
Abs (on floor), Hamstrings, Quads and Glutes
Ball on wall behind back – squats with or without weights – hold position – pulse position – full range
Ball on wall behind back – lunges – 90º with both legs – hold position – pulse position – full range
Bridge position on back on floor – heels on ball – lift one leg at a time
Bridge position on back on floor – heels on ball – pull ball towards butt – don’t let feet touch the ball, just heels – try with one leg in air
*** Immediately after these do Hamstring Stretch – one leg on ball – other leg straight in air
Kneel on floor – hands on ball – roll ball forward – then return – keep back in neutral
Ball behind knees – crunch up
Ball between legs – crunch up to ball – then crunch both upper body and ball together
Ball between feet – crunch up to ball – then crunch both upper body and ball together – alternate ball between feet and hands (don’t go beyond neutral position – don’t let back arch)
Stretches
Shoulders – kneel behind ball – hands on ball – take ball to one side then other
Hips Flexors – sit on ball – cross one ankle over other knee and lean forward slightly
Sit towards front of ball – legs open – turn body towards right leg (kind of runners lunge position) – then left
Ball in mid-back – lean back over ball – open chest – can leave arms in front – or let flop overhead
Ball in upper back – arms to side to open chest
