Raising for: TalitaKumSchool Winter Funding Campaign 2017: a school helping disadvantaged children in a small Colombia village founded by a friend - see more by clicking on the link (that is also the most efficient way of donating directly).

The Target: bench-press (i.e. pump iron) at least [bodyweight +10kg] within a month.

My commitment: to donate £2 *[kilos lifted +my age]. Pete at the gym will certify the max I press during the month.

Your challenge: Ideally, to join me and go for it yourself- adjust your target to your fitness level - come on MAMIL friends!

If you cannot join in, please sponsor me, or push somebody else to join in and sponsor them, or chip in a few quid, or just please spread the word: share on social media, leave a comment below... This is for fun, but the cause is worth it.

Full disclosure: my bodyweight is 67kg. My current bench-press PB is 70kg.

Note: the bank account linked to this is the charity TalitaKumSchool Fund bank account, not mine.

Sponsoring: maybe just go the usual simple way... i.e. commit £x if I make the target. But for my nerdy friends: feel free to make it more complex! e.g. like the formula I use, or I'd love to see caps and floors and asking me to cover you if I fail the target... go on, commit heavy, try to break me...
