Boot Camp
Outdoor group drills led by an instructor.

How to progress
Attend weekly, then twice a week. Add pace as your fitness builds.
What the evidence says
Evidence: limited
We found no trials of this particular format. Boot camps combine cardio, bodyweight strength and intervals, so the general evidence for those applies.
Take care: Classes can be intense. Tell the instructor about injuries, and scale exercises to suit you.

12-week starter plan
Start with one session a week, and move to two. Always warm up.
Tick each week as you finish it; your ticks are saved on this device only. Repeat a week if it felt hard. Weeks 4, 8 and 12 hold steady so you can settle. This is a general plan, not medical advice.
Add reminders to your calendar
Pick your days and time. You will download a calendar file that adds 12 weeks of reminders to Google, Apple or Outlook calendar.
