* Use IHE periodically, doing 5-7 days of IHE then 10-15 days without IHE.
* Continue using IHE 3-7 days/week indefinitely. The length of the IHE could be reduced to 15 minutes of hypoxia as either 1x15 minutes or 3x (5 minutes hypoxia plus 5 minutes recovery).

=Plan 1=
The main plan has the initiation shown above, followed by 15 days' rest, then 5 days IHE. This routine of 15 days' rest and 5 days IHE is then repeated as long as required.

==Plan 2==
After the initiation, there is a 7 day rest period, followed by 6 days' IHT/1 day rest that is repeated. The level of hypoxia is much lower.

==Plan 4==
Plan 4 has two IHE periods per week; 2 IHE, 1 rest, 3 IHE, 1 rest. The level of hypoxia is lower than most other plans.

==Plan 5==
This plan is intended for more extreme altitude. It follows the initiation with 12 days' rest. After that, the pattern is 6 days IHT followed by 10 days of rest. This plan has the highest level of hypoxic exposure.

==DIY IHE System==
I have built a [[DIY Altitude Training]] system that is cheap and works well. I typically use it 5-7 days/week, with 5 minutes of hypoxia/2-4 minutes of recovery, repeated for 30-45 minutes.
