Mitt hitting exercise

This is an extremely tough exercise. All you need is a pair of boxing gloves and either a partner with mitt's or another pair of boxing gloves or a boxing bag.

On your own:

30 secs left, right combo slowly

30 secs left, right combo quickly

x3 against a boxing bag

With a partner:

30 secs left, right combo slowly

30 secs left, right combo quickly

x3 either against the mitts or both doing the same thing against each overs gloves.

no rest between sets, no dropping your arms and no resting at all.

keep it fluent for the whole 3 minutes. After 1 and a half minutes it feels like your punching with bricks attached to your arms. Thanks and Good Luck.
