Thread: I need help setting up a training plan for my dad (he has lots of issues).

Hi, I'm looking for any tips/advice on modifications of his training or even his diet. His goal is to lose fat.
His lifestyle was highly stressful due to working 12 hrs 7 days a week for the last 7 years, but we sold our store last week so he's just sitting around most of the day now and this is the perfect time to try and get him to change his bad habits.
I know most beginners can’t go wrong with a full body workout focused on compound movements 3-4x a week, but given his issues, I need advice on how to modify this. Particularly because of his asthma and the leg pain.

Stats:
Age:51, weight:170 lb (he’s got a big belly now), lacto-ovo vegetarian.

Conditions:
1. moderate to severe persistent asthma
2. hypertension (stage 1)
3. dyslipidemia
4. coronary artery disease
5. gastroesophageal reflux disease ("acidity")
6. hypovitaminosis D
7. leg/nerve pain: unknown etiology
- possibly due to meralgia paresthetica
- unlikely due to pinching of nerve from spinal stenosis

Medications/Supplements:

Asthma
- Dulera inhaler 400/10mcg 2 puffs twice daily
- Prednisone 10mg once daily
- Singulair 10mg once daily
- Albuterol inhaler as needed for emergencies, up to 6 times daily
Nerve pain at legs
- Gabapentin 100mg twice daily
Blood pressure
- Nifedipine 30mg once daily
- Aspirin 81mg once daily
Cholesterol
- Simvastatin 20mg once daily
- Tricor 140mg once daily
- Fish oil 1200mg twice daily
Reflux (acidity)
- Prilosec 20mg once daily
Other
- Vitamin D
- Calcium

Training:
Right now he has just started going to the gym and doing the typical newbie garbage (ab machine, bicep curls, maybe another ab machine, and whatever else he's feeling like doing at the moment)
I'm going to have him start with the same beginner workout I started with last year, and given his condition, it will be at a super low intensity/volume, and then maybe 20 minutes of light walking on the treadmill. But I'm concerned that he won't be able to do a lot of the exercises, particularly the lower body exercises like the goblet squat/dumbbell RDLs. Would isolation exercises be better for his lower body?

Diet:
His diet has always been high carb, moderate fat, low protein (vegetarian indian food and junk food)
Also I highly doubt he's getting even half of his daily required protein so I'm going to be on him for increasing that along with his veggies, and also tracking his calories (setting up a 20% deficit)
For his supplements, I'm going to increase the fish oil to 10g, and also add in magnesium, zinc, vit c, a multi, and creatine.

Not qualified to give advice, however I think I'd be looking to bodyweight exercises, compound ones, to build up general functional fitness and strength.

So maybe something like press ups, mountain climbers, plank, reverse crunch to start off with, see how those go. Maybe 20 seconds each, no rest in between each but as slow or fast as he can go. Then rest for 90 seconds - try for 10 sets? Could build the difficulty once he gets fitter, but still with bodyweight?

Being in the gym, and trying to get fitter and healthier is a great start - I'd say that with all those things wrong, he would have to be careful, and possibly consult his medical practitioner regularly at first.
