You could try Starting Strength and Becoming a Supple Leopard.

They are both great books, although their persuasiveness is also their main flaw, because there are other views and ways of doing things.

Still, it’s best to learn about body mechanics, breathing/abdominal compression and expansion to protect the spine, external and internal rotation, toe placement, etc, before you get injured jumping into olympic lifting. Both books will give you this.

The Supple Leopard hides quite a bit in the caveat at the start, to ‘consult a physician before relying on the book to deal with an injury’. Do not read it as a self help guide to physiotherapy! It seems to contain good advice to otherwise healthy adults (note that I am not a physician!). And I do not think it is peer-reviewed – if you get injured rest and seek a doctor.

For example both books are quite clear on toes pointing outwards. Don’t do it. The closer they are to pointing forwards, the more torque you can generate in your knees and hips by rotating your hips outwards. This will put your legs in a good position and help to minimise hip injuries and problems relating to a valgus fault (where your feet arches are collapsed and your knees turn dangerously inwards, inviting ACL problems – bad, bad, bad).

But, they are both adamant that your knees stay behind your toes. And there is some strong argument against this prescription. Have a look at ‘knees in front of toes guy’ on YouTube.

I’m not educated enough to say who is right, although I am swayed towards being less worried about whether my knees are in front of my toes. I would rather concentrate more on external rotation, spinal alignment, and balancing the weight. Trying to force a ‘perfect’ posture can IME lead to poorer control of the bar, especially when I’m squatting with the bar above my head like in a squat snatch. For example, if I force my knees back behind my toes and have to compensate with my shoulders where I lack the flexibility to keep my shoulders rotated properly… I’d rather let my knees go forwards and protect my shoulders (and minimise the risk of dropping a heavy bar on my head). Automatising external hip rotation through back squats, and later front squats (more of a support squat IMO), however, tends (with me) to sort out my knees, anyway, though.

As for a workout routine, I agree with others, to build up with the free weight barbell exercises before tackling more advanced lifts. Keep it simple for a few weeks / months. Squat. Bench. Deadlift. Overhead press. Pull ups. Rows. These are the essential compound lifts.

The benefit of a barbell over dumbbells is that you can ‘bend the bar’ to ensure good shoulder rotation and increase torque / strength.

You can warm up and practice your olympic lifting form with a sturdy broom handle. E.g. hold the handle in the air in the position of a snatch. Shoulders rotated correctly. Abs tight. Breath in to your abdomen. Rotate the hips outwards. And squat with your body weight, keeping the ‘bar’ above a centre line at all times. It’s harder than it sounds, as adding weight forces balance, whereas an empty broomstick can wobble all over the place.

Six days a week is going to be tough with a strength-training routine. It is just about manageable if you keep the lifting reps low (always warm up first!) and, depending on the routine keeping the weight low (e.g. 5*5 at 60% of your one-rep max for the big lifts on a push/pull split of compound lifts).

Others may disagree. If so, I’d be keen to hear where my advice is wrong.
