options: isometric or isotonic

1. ISOTONIC contraction

Lifting a weight 10 times is a kind of ISOTONIC contraction.

Lifting heavy cans and putting them on a shelf may be called an ISOTONIC contraction.

Lifting your heavy book bag several times is good ISOTONIC contraction.

Isotonic actually signifies 'same tension,' where 'iso'- signifies 'the same' and 'tonic' alludes to 'tension or force' - for this situation, in the muscle. Isotonic contractions keep up consistent strain in the muscle as the muscle changes length. This can happen just when a muscle's maximal power of compression surpasses the aggregate load on the muscle. Isotonic muscle contractions can be either concentric (muscle abbreviates) or flighty (muscle extends).  

2. ISOMETRIC contraction

Holding a heavy machine part steady while securing it in place may be categorized as ISOMETRIC contraction.

Flexing your leg muscles and holding the flex is an ISOMETRIC contraction.

In an isometric muscle contraction, the muscle fires (or actuates with a power and pressure) yet there is no development at a joint.  

As such, the joint is static; there is no protracting or withdrawal of the muscle strands and the appendages don't move.  

In this kind of muscle contractions , there is no adjustment in the length of the muscle filaments themselves, and there is additionally no development at the joints, yet the muscle strands still fire.

is this a genuine question or is it on a quiz or something? lol
