That would depend on if you had access to weights or not.
If you do have weights, stick with the barbell.
You can load a barbell heavier than dumbbells, kettlebells, etc.
My choices would be
(Kendrick Ferris, Jr.)
- bench press
If barbells are not available, use odd objects, for the basic lifts mentioned above.
Odd object lifts are way harder than an equivalent amount on a barbell lift.
(Martin Jancsics )
Modify the movements to fit the type of object you are lifting.
The most basic of all exercises are done with your own bodyweight.
- push ups
- pull ups/chin ups
There are many ways that your life can depend on how fit and strong you are, whether it is an emergency situation, a physical confrontation, or just daily living. Sports and competitions are important, but not as important as the quality of your life overall. You have to be able to move your own body or external objects as the situation requires it day by day.
You don’t need a bunch of different exercises, but whatever you choose, always give 100% effort and focus to it.
Be consistent and watch what happens!
