You don't need a fully stocked gym to get a full-body workout. The Lifetime Ladder program ensures you can do this for a long time with increasing levels of fitness, and lowers the barrier of entry to anyone, no matter how fit you are right now.

This is what it looks like:
The program is organised around a "fitness ladder" with 48 rungs. Each rung prescribes a given number of repetitions of five exercises. The first 15 rungs constitute the Introductory Ladder and involve easier variants of the exercises in the Lifetime Ladder, rungs 16 through 48. The exercises are intended to be done every day. Completing all the exercises typically takes between 10 and 15 minutes.
Spend one week on each rung. On a given day of the week, for example Sunday, try the next higher rung. If it seems as easy as the current rung felt the week before, move up to that level. If you have difficulty completing any exercise of the new rung, or you can't complete it in 15 minutes, or you feel pain or exhaustion at that level, stay at your current level for another week.
The Introductory Ladder starts you off with bends, sit-ups, push-ups, leg lifts, spot running and jumping jacks — don't worry, these are mild versions of how those exercises are usually done. The idea is that even if you are out of shape, you can do these by starting at the first rung and working your way up.
The full Lifetime Ladder exercise plan and details on how to do each exercise can be found at the link below. It's a long read, but make sure you go through it carefully before you start the program.
